Magnus, looks like you opened up a new frontier, thanks to your Dad. This is something I had not heard before. I had the stalling issue, but usually it started right away after a lot of research, the dealer replaced the crankshaft positioning sensor and it didn't have the problem again until I sold it.

I have a 2001 grand prix that has 170000kms on it, always serviced and in good shape. It will stall randomly, whether I am stopped or going 50km. Some times it starts perfectly and others it has to be cranked over a couple times and then will shake like crazy, blow blue smoke out the mufflers, RPMs with rise and fall and then it quits. The oil and battery light comes on and thats it. After it stalls sometimes it starts right away, others can take 5-10 minutes. It has been to the GM dealer and hooked up to the computer, where they found nothing. The dealer is trying to tell me it is possible I blew a head gasket and coolant is now running into the motor and causing the smoke and for it to stall when the motor isnt hot enough to fire. Normally when your car is burning coolant it blows white smoke though. Said I need a new motor or to rebuild it. I feel like Im getting shafted, and will not fix it, as my car is not worth enough to spend the couple grand. I also see several related problems with CPS and ignition control modules and such. Has anyone has the same problem with the stalling and blue smoke

Ive got a 2006 grand prix with a 3.8. We just put a new transmission in it a week ago and it has just started the stalling thing, usually first thing in the morning it will shudder with the idle going up and down and then it will smoke and stall. my "Anti theft not programmed" message is showing up. also my remote for auto start and auto door locks have quit working, i have scanned the codes and all that comes up is PO108, it is really driving me crazy, please post if you find out what yours was.

#363 of 367 2002 Grand Prix Stalling Out and Choking
Jul 07, 2013 (2:28 am)
I'm not sure if anyone can help me. I have a 2002 Grand Prix SE 3.1. It stalls out randomly while driving at low speeds or when stopped, it doesn't do it all the time but very frequent when it is. I had the alternator checked and replaced thebattery, cam shaft sensor, crank shaft sensor. I also completely cleaned up the ground to the car and what it was aattached to with no change. I can't seem to find a dealer or repair shop that can figure out the problem. It also at between 3000 and 4000 rpm will choke reallly bad and not gain any acceleration.
I'm not sure if this is 100% but for the past week I have had it under half tank of gas and no issues what so ever you could step on the gas and no choking nothing but then I filled it last night and it started choking and stalling again. When it was doing it originally I had 3/4 of a tank. I just bought this car 2 weeks ago. When i drove it home had about 1/4 tank of gas and no issue at all. So I'm not sure if im just nuts in thinking gas has anything to do with it or not. Any advice tips or any information would be greatly appreciated! !!

Sounds like you have replaced quite a few parts but I didn't see you mention the Mass Air Flow sensor. Have you had it checked or replaced? It is not a cheap part but on my 3.8 liter engine it is a 5 minute job, you can do yourself.
You don't have to get an original GM part but stay away from re-manufactured parts, I had to get a new non GM part. It solved the problems I was having which were very similar.

In my 2001 Grand Prix I had a spare key made and hid it in a magnetic box under my car. I misplaced the original key and tried to use the spare one and after the car started it would die after a couple seconds. In the end I realized that nothing was wrong with my car and it was the key. Original keys have a chip inside them and when I tried to use the spare the security system would kill the car because it didn't have the chip in it. I was so relieved to find this out because I thought something was wrong with my car. I wanted to tell you thanks because it was this post you made that tipped me off to the possibility of a security issue vs. engine trouble. I found my original keys so I'm all good to go now. Thanks again!
#366 of 367 Hard starting, weird idling when warm
Oct 06, 2013 (4:51 am)
On my 2005 Gran Prix the car will start fine and drive well when it is cold. If I go to the supermarket and let the car alone for fifteen minutes it doesn't want to start right away and then the tach swings around wildly. I put the car in gear and it lurches with almost no power. The mechanic fiddled with it last week cleaning the throttle body but it is doing the same thing. I just replaced the o2 sensor upstream as well as the mass air flow to know avail. Can anyone help?
