My grandparents gave me their 2002 Grand Prix for my birthday in 2006. I had the same problem. I took it to the dealer multiple times and they kept telling me that they couldn't recreate the problem. Being an 18 year old girl at the time, I think they just brushed me off. Finaly, I was walking back to my car with one of the other mechanics and told him about the problem. Ended up being something there was a recall on! I don't know if there's a way to check recalls anymore since their out of business, but thought that might be helpful.

99 bonneville by: Mak
I doubt that this is still open but its worth a shot. My 99 Bonneville is have a similar issue. It stalls when it gets to normal operating temperature 190-195. Then it takes like 20 minutes before I can restart it. I replaced the crank sensor, the air filter, fuel filter, thermostat and cts. Not sure what to do next since the problem is still current. HELP

I also have a 2002 Pontiac Grand Prix Intermittant Stalling by: Anonymous
Hi there, I too have a 2002 Pontiac Grand Prix and also love this car. It has been working great, however the other day I was driving the car, and as I pulled out of my complex it "bogged" down a bit but continued to drive. It started to rain (downpour) and I went through a couple large puddles and it seemed after that my car continued at a stop sign and then lost all power. I put it in park and started it right up, went to put it in drive and it died. I waited a minute, tried it again and the same thing, starts right up will even stay running in park, put it in drive and it stops running. I then waited about 3 minutes, started it and was able to get it to go for a while and then it started to bog down again. It rode for awhile and then died. Again, it would start right up, but the minute I put it in drive, it dies. By this time, I was able to get it off the road and let it sit for about 15 minutes. I called and spoke to someone who said, it's probably because I have something loose and the water from the puddle got in there and was making it do this. I was told to sit for a while, try to let it dry out and then see. I did all that and the car did start and I was able to get it home. I left it there overnight and the next day we tried it and the car started and ran just fine. Two days later, I'm riding home from work and it's running fine. It starts to rain pretty hard and the car starts to bog down and sputter again. I pull over into a parking lot and sit for a good 10 minutes, the car runs fine and I get home. At this point I'm thinking maybe the "wet" theory is correct because this seems to have happened twice while it was raining. WELL, now I'm thinking it's coincidence because the day after, I get up and it starts and it's not raining, sunny day. I'm riding the car to work, it gets off the interstate working just fine, I come to a light and the car dies. I go through the same panic steps. Put the car in park, start it/ it's starts right up, put it in drive, it dies. Again and again and again. I call my boyfriend, he says try it in neutral, so I put the car in neutral and it runs, but again, put it in drive it dies. After letting it set for about 3 minutes, I'm able to put it in drive and it gets me to work about a mile a way but sputters slightly. Your opinion, advise, help will be greatly appreciated. Thanks!!!

This might work. by: Anonymous
I think it is the same problem like the 02 GMC Yukon has. The camshaft sensor is going bad. The cam sensor has a hot wire that feeds the ecm (computer)a signal showing what cylinder is firing and when to send fuel to each injector. That fixed the Yukon. It might fix yours too.

Similar Stalling Problem by: Anonymous
Not sure if this is still active, but I've got a similar problem with my 01 Grand Prix. It stalls consistently within 10-15 miles of each outing. It will not restart because it throws the MAF P0101 code. I have a scanner that I use to reset it..thus allowing it to re-fire. I have replaced the MAF sensor, PCM computer with latest flash firmware and the problem still exists. The P0101 code is 100% consistent every time it stalls. I keep reading about the crankshaft sensor and it's either that or finally get it into a "reputable" dealer. Thanks.
Steve Says,
There are several other things that you need to check. The first thing you should check is if there are any vacuum leaks. If there are it can cause the MAF to read incorrectly. Also, if the Mass Airflow Sensor does not have a good ground or if the wires that go from the PCM to the MAF are faulty it can cause this problem.
Another thing that might cause this is the BARO sensor. The MAF uses this sensor to calculate the airflow into the engine.
You will also want to check to be sure that there are no restrictions in the incoming air tubing or the exhaust. This could also affect the MAF calculations.
The last thing to check is the throttle body. It needs to be clean and free of debris. Part of this check needs to be checking the TPS (Throttle Position Sensor) with a scan tool to be sure that it is working correctly. If it is not it could be giving faulty readings to the PCM which can cause MAF codes.
