A few months ago it stopped running and wouldn't start.A buddy of mine who is a mechanic told me to replace the crank sensor so I did.problem solved,well its only been about 3-4 months and now car is spitting and sputtering real bad.It was doing it before the crank sensor went out and now it is doing it again.Can a crank sensor go bad that quick or could it be something else?But it is doing the same exact thing as last time.should I replace the crank sensor again?PLEASE HELP!!!!! thanks

I have a 99 Pontiac Grand Prix GTP Super Charged 3800 Series II Engine. I was experiencing stalling issues like a mad man. When I'm at a red light it'll stall, when im at a stop sign it'll stall when i accelerate from a stopped position guess what? Yep, it stalls. I tried everything from changing the MAF, Spark Plugs, Cleaned the throttle body, tested the fuel injector you name it I did it. One last idea came to mind and that was to check each cylinder coil and module. I took the cap off of cylinder 1 and 4 and it was pitch black! Meaning it was not receiving constant sparks from the plugs which cause all of my stalling issues. I call the dealer the wanted to charge me $586.00 plus tax to change them out. Well guess what, Im not even good at working on cars but I was able to change the cylinders and module by myself. Very east to do on my car. The parts cost $21 for each cylinder and $127 for the module. Car is running like a CHAMP!!!(knock on wood!! : ) Hope this helps anyone with stalling issues. Thanks for all of the help you all have given me. |

I recently bought a 2001 grand prix gt. Everything is great (well there is that weird key stuck in ignition thing-but i know how to fix that anyways) the only thing that worries me is every now and then when accelerating the shifts seem a bit jerky, accompanied by an almost inaudible whine. Otherwise the car shifts smooth as glass...yes, the tranny was serviced at 76,ooo mi. it now has 93,ooo mi. so that shouldnt be the problem right?? i heard it might be the computer increasing the pressure in the tranny but why would it do that? any help please? thank you

Have never experienced any problems with this car until now. Car has 115,000 miles. 35,000 in the last year. Day 1 the driver side air (dual air) stopped blowing cold, passenger side blows even colder now. Day 2 Air seems back to normal. (Probably unrelated to this issue). Day 3 Drove to work everything seemed fine. At lunch after car started it seemed to run a little ruff and the gas petal was 'hard' to press the first time. Seemed to run fine but idled ruff. Temp gauge ran higher than normal but did not run hot. Drove after work for about 2 miles ... car started to run hotter so had the car towed home BEFORE it ran hot. Car now will not start, it cranks strong but does not start. Fuel appears to be flowing.
