Ok, This is interesting.... My wagon has heat..when it wants... I turn the heat on-nothing comes out. Pop the hook-tap the fan-instant heat. Is something just stuck in there? Or could it be something more?

Hey guys, I don't even know if anybody remembers me, it's been a real long time. But anywho... before I start I want eveyone to know that my father is the king of knowledge when it comes to knowing about my car (or any car especially GM, hes been rebuilding engines and doing body work on cars since he was 14 years old, and is currently the service manager at a Chevy dealer in PA) but I still want some advice because he's in a state of denial because he has to find a way to get her intake leak fixed, and now solve my new issue, which is why I'm here. Sorry that took so long. The issue is apparently "sticky lifters", which we are assuming was caused by sludgy oil (since…

So far we've been through 2 full tanks of gas since owning the car. The first tank got 218 miles on it...divide that by 17 and the car got a mediocre 12.8 mpg. Considering this is the base V6 I'm scared to think what the 3.0 and 3.5 would get! In it's defense, this was mostly city driving. So far, on the second tank of gas I've got 250ish miles on the odometer with still gas left. This was more highway-like driving, since I took it to school this past week. Still, I don't think I'll break 20 mpg on this tank. What makes me sad is that Saturn's big new Outlook gets 20 mpg average in a mix of driving (according to Autoweek) So, and suggestion on way to improve fuel eco…

If you guessed Intrepid...you'd be... Wrong. Not the Shadow either. (both of those Dodge's transmissions shift fine, much to those who say DCX transmissions are crap) It's...the Geo Prizm! Yeah that's right, the one with "Toyota Quality" Yesterday (which was freezing), I set off too school but first went to Shell to get gas. I pulled in and gassed up. Turne the car on and went to put it into 1st...and it wouldn't go. 2nd...no...3rd...no...4th...no...5th...that's be a "f@#k you asshole I don't feel like moving" no.

So I today I decided to check the fluids in all the cars and I noticed the Intrepid needs oil (no surprise from what I've been reading). Anyway, I went out and bought some oil for it, but now I'm wondering what's in there: synthetic or natural oil? How can I tell the difference? It's possible the last owner switched it to synthetic oil to avoid sludge buildup the 2.7L is so notorious for. I'm pretty sure bad things would happen if I pured regular oil in and it had synthetic inside already. Help would be appreciated! (especially so I can get it done tonight). Also, when it comes time to change the oil, and after the engine has been steam cleaned (because oil was found on…

I was wondering what engine I can go with if i keep my stock transmission. I have the olds 307 right now. I was thinking about the supercharged 3.8L v6 off gm parts direct. I'm pretty sure my trans can't handle that though. Anyone have any good ideas, I'm still open to what engine combo I will use. I would just get another 307 but I really wanted more miles per gallon. Also what transmissions would look good to put in for different engine combos?

Can a 2.2L Ecotec easily be put into a 1999 Sunfire that only has the 2.2L? I want to know because I heard that the 2.2L are pretty shotty but the Ecotecs were significantly better. Could this be done without switching out the tranny? The engine in it is fine but once it starts getting into the higher mileage in the future. Also what else would need to be changed? Also, can G5/Cobalt rims be put on a 99 Sunfire and are they the same bolt pattern. They both have the 5 wheel nuts but I don't like the look of the wheel covers.

I have a 2005 Chevrolet Malibu MAXX LS and I would like to use my MP3 player in the car. I have never been satisfied with FM transmitters. I noticed that a bunch of the newer GM cars have a radio with an auxiliary in port on the front that would allow me to plug in my mp3 player and not have to deal with the lousy FM quality sound. I'm wondering if I were to buy the radio from something like an 06' Impala or 07' Tahoe if I'd be able to have it installed in my car and have everything work. As you all know, the radio in the Malibu handles a lot of the car's readouts, such as oil life, gas mileage and so forth. I want to make sure I don't lose those. I compared pictures…

Yes sirs, my new truck is in. 2007 Sierra regular cab shortbed 2WD. It's a goodlooking truck, to be certain, however, the rear end sits a bit too high for me, it has a definite rake. Lowering blocks seem to be a simple solution. Question for anyone who knows: If my truck has progressive rate springs, that means the more pressure that is put on them, the harder they'll ride, correct? Do lowering blocks compress the springs? Can I install a set of 2" lowering blocks to level the ride height of my truck without affecting the ride? Sorry to sound like a dummy, but this is out of my line of experience. Thanks in advance!

Hey guys, I expect to be leaving my Regal parked from mid-June until the beginning of August. I will be out of the country. I will be taking the car up to Portland but, since my Mom doesn't drive, I wouldn't even want her to start it and move it up and back a few feet to get things moving...though maybe a neighbor could do it. Still, it may wind up sitting there. I've heard that leaving them parked for that long can cause some problems. Namely, the battery may fail but more so than that, tires are supposed to get a "flat spot" or something to that effect. Is there any truth to that? What other car components could be adversely affected by being parked for a long …

After trying to figure the light out for a while, I think I might have figured it out... Turns out-it looks to be idle air control valve. Though this gives me a few questions to ask.. Could this be the major cause of my shaking at idle? (and my all-over mpgs?) I was told this part lasted a bit too long..true? (140k) I need to know a little more about this little guy...as I thought I knew what I was doing... While replacing this, I was planning on replacing the fuel filter and Pcv valve too... Any suggestions? (expect for setting it on fire and rolling it down a hill.. )

I've noticed the wagon has been sluggish lately, and running pretty rough. But since it has starting getting colder the last few days, it somehow seems to run better... The idle isn't as rough, a bit more pick up (not much) and pretty much stays that way even after running for a while. It weird that it is affected by weather... Could it be a sensor? Everything else Haven't checked all hoses yet, though) I've been betting on the EGR... What do you guys think? Ask me anything....

So I noticed today someone put a very small ding in the front fender of the GTO I took a picture, and it doesn't show up that well but you can see it because of the high-resolution. It's in a rather odd place and I'm not sure if it can be popped out, so I thought I'd ask to see if anyone knows. The ding is in the upper part of red "circle," above the crease in the wheel flare.

Okay, so it's no secret that my ass is quite lazy. Remember that miss at idle? I never did attempt to fix it. It only did it during idle and it never gave me any problems since... until now, that is. It now misses while there's a heavy load on the engine, especially in lower RPMs during acceleration. Going up hills will just kill it, as it will begin to miss and cause it to be nearly powerless with a bit of shaking. Luckily, I'm able to shift down by the push of a button without accelerating and avoid bogging down. One thing I just recently noticed (never thought about it before, stupid me) is that it will only miss once the engine is up to operating temperature. Now, I r…

I use 5w-30 motorcraft oil and change it every 3 months because i never reach 3000 miles on it.

I can hear the tranfer case shift, and it does sound much louder then my friends Silverados, so not sure if I should be able to hear it that loud. I do have 92,000 miles on this rig.

My wife purchased a 2003 Envoy brand new and it has always had problems with overflowing at the gas pump. It doesn't happen all the time, so I can't seem to figure out if it is just the position of the pump spout, or a defect part. We haven't mentioned it to the dealership yet, but my sister-in-law has the same vehicle(SLT vs. SLE is only difference), and experiences the same problem. I believe she has spoken to the service department about it, but can't recall what they responded.

When my car's cold (within the first 2 minutes of driving) any big bumps (think 2-3 inches suspension travel) cause a squeaking or scraping noise from the right front tire. It kind of sounds like the springs in a really old bed, if you were to jump on it. It gets quieter almost right away, and after the car warms up, it goes away completely. I took a look at the tire, and nothing looks out of place. I'm going to take it in to a dealer tomorrow - hopefully it's under warranty, whatever it is. I was just wondering if anyone here had any idea what it is. Remember, it's an '05 Cobalt LS coupe.

I'm buying winter tires for the Cobalt this winter (Michelin X-Ice). I'm trying to decide what to do for rims. I was initially going to buy steel rims to mount the snow tires on so I could put them on and off myself. The salesman told me that since I had the OE rims on there, there was really no point in buying steel rims. Only people with expensive aftermarket rims really need them. I don't think he was trying to screw me, since he knew I was just buying the tires there and not going there to have them taken on/off. He also said that the tires would need to be balanced after installation and removal whether they were on steel rims or my original ones. I don't really un…

OK. So when ever I take a sharp corner, regardless of speed, I hear this weird klunk from the front end. I have a single idea at what it might be, and that would be tire rods. Yes? No? Maybe so? Also, what would cause the speed setting on the wipers to change. Like sometimes in the fastest wiper setting, they are imtermittant and vis versa. Turning them off and turning them back usualy does the trick. And finally, my indicators are telling me that my rear window is open when it closed. I think the latch might be loose. Cheap part? Hopefully :] Thanks for any input. [except calling me teh n00b. not allowed.]

I got through washing and waxing my car this morning to find a ding, slightly smaller than a dime or even a shirt button and not deep at all, on the front of my hood. I've no idea how it got there, but the paint is all there so I doubt it's from road debris. Anyway, it's in a spot on the hood where there's double metal (near the latch/release), so the traditional PDR method of working it out from behind is impossible. Do any of these "glue on suction cup" ding removers (like the Ding King, et. al) actually work, and is it something I can pull off myself without making it worse? Is it even fixable at all without filler and respraying the paint. I'm willing to bring it to a…

Alright, ever since I had my Millenia, it idled a bit rough as the engine seemed to miss. However, once moving and pressing the accelerator, it stopped and ran perfectly. Well, every once in a while it would suddenly run as if a spark plug was bad. It would bog down, but still be driveable, barely. Then it'd suddenly stop. I thought maybe the fuel injectors were dirty and possibly clogged so I tried some of that STP fuel addictive made for that. No real effect. Lately, I tried changing the spark plugs to some Bosch Platinum 2s. Still no real effect on any of them, but luckilly it has yet to get into one of its bogging down fits.

For some time now the Shadow has had some stalling issues. Usually this would happen when the car was cold, and almost always on cool/colder days. In the winter it was a bitch until the car warmed up. It would stall either when coming to a stop and almost being stopped, or when just starting to accelerate. Since I got back from Kansas I have discovered that it stalls when going in revers. Not always, but sometimes it will either want to stalls, and the tack swings wildly between 0 and 1200 RPM...sometimes it stalls, sometimes it doesn't, but it sounds like it. I think it might be the throttle body, but I'm not sure. It's a fuel-injected 2.5 4-cylinder. Any thoughts? It'…

It's not tucked under the seats or any of the other interior panels (which are out of the car). Is there any way at all to retrieve the option code information given the VIN of the car?

A friend of mine has a '01 Silverado that has just started to make a loud and "oh so very not happy" RPM related tapping sound when the engine is cool/cold. Noise appeared to go away when the engine heated up, and to his backyard mechanic's ear, it sounded like a sticky lifter, loose valve lash or other valve train related problem. As he had some other work to be done on his truck that required some professional expertise, he took the truck to a GM dealer workshop. He was totally not expecting the cause of the "valve train" noise to be driveline related, namely a cracked flex plate. GM used to be notorious for blowing flex plates.

Situation 1 - Start at 120 km/h at top - Push in clutch, let car idle to bottom where it would be at about 100 km/h - Accelerate back up to 120 km/h gently Situation 2 - Start at 120 km/h at top - Leave in 5th, take foot off gas, going about 85 km/h at bottom - Accelerate back up to 120 km/h gently I usually just leave my cruise on, because I don't want to slow down just to save a little fuel. On a side note, I found out that …

For my pontiac 1994 sunbird 2.0 sohc, my water pump started dumping out antifreeze today. I know parts aren't expensive but how much should I expect a shop to replace it for. I figure do the timing belt at the same time as well since they have to take it off anyway right? I hope its not over $500.00 because thats all I'm willing to spend and I don't feel like trying to fix it myself since I don't have much time.

So I found this awesome white '94 Z28 with ~88,000 miles on it, and all I'm waiting for is the finance guys to tell me where to sign. But, I'm a little concerned about fuel economy. I'm going to assume that the MPG on a 12-year-old V8 aren't going to be great, and I can accept that. My question is are there any ways that I can mechanically change the 5.7 (LT1?) that will increase my fuel economy? I've developed a pretty economical driving technique by driving my parents' Tahoe, XC90, and S80 T6 over the years, so I'm looking for something that will help post some worthwhile gains combined with that. Thanks.

A coworker of mine asked me if I knew anything about Caprices and electrical problems. I told him that I'm no mechanic, but know plenty of people online that I could ask (um, that means you guys!). He has a 1991 Chevy Caprice with the 305 V8. He was given this car by his uncle about 7 years ago. When his uncle owned it, right before giving it away, the radio was replaced due to being shorted out. John, my coworker, had to replace the radio again about two years after he got it. The first indication of an electrical problem (other than the shorting of the radio) was that the door locks would hum & vibrate - until he turned the car off. The latest issue he has is…

Suppose I get one of the cars which cheap, conservative and cautious Trinacriabob drools over (LaCrosse, Grand Prix or Monte Carlo). I then don't order the BIG option package with everything in it but still want the feel of the leather wrapped wheel. (Trust me, from rentals I've had, it makes for a different driving sensation than the urethane wheel). Is there a way to add this feature (leather wrapped wheel a la factory) without pulling the steering wheel off or at least doing it after the fact with some amount of ease? I would we willing to let the dealer do it. Let me know if you have any ideas/opinions.

Ok, time to change the plug wires. Brought a dirty change of clothes to work and so did a co-worker who is very cool and helps me with minor items. Have a 3800 V6 in W-body Regal. Got the 3 in the front in about 10 minutes. It cranked over fine, so I did it right. YAHOO! Started in on the rear firewall plugs. Took of the manifold decorative shroud and the clips for the plug wires. Good God. There are these heat shields around each plug and he and I tried EVERY plug and we couldn't pull ANY of them. We tried pulling on the rubber boots and then on the heat shield... NOTHING on any of them. WHAT'S THE DEAL? I mean...my hand clearly reaches every plug. I…

All right, from what I've read on here, and elsewhere, Direct Injection is going to be the new fuel delivery system on a lot of vehicles. Just a few questions about it. When I think of direct injection, I think of diesel engines with an electric supply pump from the tank, then an engine driven Fuel Injection Pump that boosts the fuel pressure up insanely, finally ending in a fuel injector that shoots the fuel directly into the combustion chamber. Is that how a gasoline-burning DI vehicle works also? And if it does, then how does the fuel mix with the air and become atomized? Another thing, wouldn't that do harm to the injector since its exposed directly to combustion…

Mom finally gave up on fixing her Taurus wagon. So I took her car shopping. She looked at a Passat wagon, Vibe, Vue, L200 and a Malibu Maxx. She was planning on a late model used but later decided to spend the extra couple grand and buy new. So her local Chevy dealer found her an 06 Maxx LT with a couple extras, sunroof, side air bags, XM. Very nice little car, I was very impressed with the solid feel of it. So anyway, my reason for posting.... I'm pretty comfortable with GM's 3.1, 3.4 and 3.8 V6's. But I don't know too much about the 3.5. I'm hoping someone can enlighten me on the changes (as compared to the previously mentioned engines). Is this just an up…

Less than three years ago, I had a pressure control solenoid installed in the transmission on my 2000 Century. It cured a intermittent hard shifting problem and whine when starting out from a stop. I could usually stop this problem if I turned off the ignition for a few seconds but this became diffcult in stop and go traffic. The problem is coming back, about once or twice a week. Is this a known problem? Is there a TSB? Should GM help pay for repair because the same part has to be replaced?

We have a 1995 Buick Century with the 3100 V6 (160k), which recently developed a stalling problem. The problem happens when the engine is warm (although I don't know if engine temp has anything to do with it). Irrespective of engine or vehicle speed, the motor simply cuts out. No warning. No hesitation. No stumbling. And then it takes two or three attempts to restart the vehicle, after which, the engine performs flawlessly. There are no codes in the computer, and my mechanic can't find anything. I'm baffled... I'll be away from my PC for most of the weekend, but appreciate any suggestions made in my absence. Thanks for your help!

They couldn't find anything wrong with the car. Two weeks later the battery was dead again. I had it towed dead so that they could find the problem. I was told that the battery was no good and it wouldn't hold a charge so they replaced my battery. Everything was fine until the beginning of February, again I had a dead battery. I had it towed again and still couldn't find the problem. The dealership called GM Tech Support and they said that I don't drive the car enough to recharge …

I know that when this technology was newer, the cast iron block and aluminum head could be a problem if the engine ever overheated and it warped the head gasket. I know of a friend's parents with a Thunderbird this happened to. However, I don't hear much about this anymore. The Chevy V6s, 3.1, 3.4, 3.5, 3.9 are all cast iron block/aluminum head. Most engines are like this now. Only the 3800 and a few others remain as iron block/iron head. Do you think this is a cause for concern? Have they addressed the fact that a car can run a little hot? Any thoughts or opinions?

After years on driving with my elbow on the center console cover in my Regal, the vinyl now has a dimple/tear about the size of a quarter. Incidentally, it's burgundy colored vinyl. No big deal, but if it's a cheap fix, I'll do it. The console cover comes off so it can be taken somewhere. What's usually involved in something like this? Is it expensive? I know that, when used cars come in, they are accustomed to making these fixes.

Never a problem going down. And when it stops, all I have to do is lower the window again an inch or two and hit up and it closes all the way. Any ideas? No other problems with any of the windows in the car.

At nearly a quarter million miles, I will be buying a set of 4 new tires for my Regal W-body coupe. It is currently on its 3rd pair of struts. I will replace the front struts. They don't cost that much. The rears are a different story. They are considerably more expensive and I've never figured out why. Currently, when you push down on the rear, it's as firm as when they were new (about 60,000 miles ago) and there is zero bounce. However, on the right rear side, I think the bearing plate has gone south because when you go over a bump in a diagonal fashion, you get a nice clanking sound. Also, the rubber boot around the cartridge has a tear. Two questions: 1. …

A metallic, vibrating sound. Oddly enough, it's not really present at a dead stop or park. It's mostly prominent at low speeds (probably because I can't hear it at high speeds). It comes from under the hood. Sound #2: A whirring sound that's getting louder and louder as time goes on. Say you dr…

I have never owned or ridden in a flat engined vehicle but have found myself very intrigued recently by them, both the Porche flat 6s, Corvair flat 6's, and also the Subaru 3.0 and 3.3 flat 6's. Has anyone ever made a flat 4, a flat 6 with 2 cylinders chopped off? Would this design not be as or more stable than an I4 or a boxer 4 (like the Subaru 4's)? What about flat 8s, they sound like they would be very well balanced and be as low as flat 6's and they would have more area of combustion? Would not a flat 4/6/8 engine architecture be the most cost/engineering effective series of engines to build and package? Why aren't/haven't there been more out of the V (play o…

I'm not going fast enough to actually slide the tires, probably about 10 mph. They're tight 90 deg corners, so I probably have to turn the wheel about 270 deg to make them. Right at the point where I have the wheel turned the most, just before I start unwinding it to go straight again, I will hear a squeak from the tires, I believe the outside one.
