Hey im having the most problems out my car since i paid for it. Well about 3 weeks ago my car started shaking so bad and my exhausted pipe was putting out a horrible smell. I took to the Amoco the man put it on the machine and he said it said that it was my Chore. So my car have three and he checked all three and my first one wasn't giving no fire. So I had it changed but about 2 days later it started doing the same crap over again I took it back and the same Chore had went back out. So it got replace again, now I was taking my little boys to the bus stop and it started shaking again but this time it went dead and when I finally got it started back up it barely would go. Please help me!!!!!!

Mine issue ended up being the MAP sensor. Haven't had an issue since this was replaced!

If you have a good diagnostic GM mechaninc tell him to run a fuel injector balance test with a noide light. He may find a bad injector. If so consider replacing all of them. It may be costly but if you have a good car its worth the investment.

I had this same problem with my 2003 grand prix gtp - the crank sensor was failing. After replacing that sensor everything works fine.

I made the original post for this thread about my 2003 Pontiac Grand Prix GTP that dies mysteriously. Posted Jun 08, 2008 (11:11 am)
What fixed my stalling issue was having the crank sensor replaced.

You may have your issue resolved by now but if you haven't, here is some info. As you can see multiple folks have different suggestions. I have had both MAP (mass air sensor) and the crankshaft positioning issues. When MAP fails, car chokes a little when you are accelerating, the engine may or may not stop, also your RPM will fluctuate when you are idling occasionally the engine killing. You get a MAP code. The crankshaft sensor figures out the firing order of the cylinders, when it fails, the engine stops at any speed, you could be on the highway doing 70. Fortunately, after you pullover, and put the car in park, it will almost always start. More than likely there won't be a code thrown that's why crankshaft sensor problems are tricky. If you have a failed fuel injector, the car will run rough almost always but it shouldn't stall especially with a 6 cylinder engine.

I am having what appears to be much of the same problem as many of you are having and I need help. My 2004 Grand Prix GTP has around 73000 miles. Back in november my car wouldnt start. It would crank but didnt fire. My mechanic replaced the fuel pump and the car ran fine up until a week ago. I had my car running idle for about 15 mins with my wife in it, when i came back to the car she told me it started to run rough and a light came on. She turned the car off and couldnt remember what light she saw. A week later as I was driving home locally my car cut off, my traction control warnings came on saying service, I was able to get it to restart only for it to cut off again a short time later with the same results. My mechanic said the fuel pressure was low so they again replaced the pump. Got the car back and it ran fine for 3 days and again driving locally it died again with the same indicators lighting up and wouldnt restart. To make note, I dont even hear the pump hum when the key is turned on. Please tell me my pump has gone out again. Its barely 3 days old. I dont know if it could be the crank and cam sensors or the ignition module or if there is something else going on. Any ideas and advice would be appreciated.

Get the crank sensor replaced....
That is what is causing your car to die....

Thank you for your quick response. I appreciate that. I kinda thought so because I had this same problem with a 99 chrysler 300m but after reading many other posts on here I just want to be sure. Have you had this problem too? If so did this rectify it and did you replace it yourself or take it to a shop?
