Replying to: jessewoo15 (Oct 13, 2009 3:25 pm) Hi Jesse,   Too bad that what you did to the grounding cable did not fix your problem, My '99 Grand Prix GT was stalling up to 3 times per day until I cleaned and removed the paint from the grounding point. The stalling stopped immediately and I have driven over 8000 km (5000 miles) in one month since then (I have to drive into Detroit almost everyday for the past 4 weeks and desperately needed to have that problem fixed). Since I did not spend a penny on the fix, I bought an OBD-II analyser (on sale) with the money I saved so that I don't have to run to my friends to check for error or pending codes. By-the-way, there were never any codes tripped after the stalls. The key to see whether your grounding cable is a problem or whether you have fixed it properly, if it is, is to use a multi-meter to check for voltage drop or resistance that should not be there. A consummer grade digital multi-meter costs about $25. It is worth getting if you don't have one or can borrow one easily. You should confirm the engine, therefore all components such as PCM, sensors, etc. are seeing the full battery voltage. The unwanted resistance may be in a different part of the circuit. A multi-meter has many other usages too. Good luck! Replies to this message: jessewoo15 (Oct 24, 2009 10:15 pm)

Replying to: pat_from_grove (Oct 14, 2009 2:00 pm) The dealership replaced the Mass Airflow Sensor and I've been driving it for 2 days now without any stalling issues. Too bad it was after a PCM ($1000) and Ignition Contol Module ($400) and Crank Angle Sensor ($400). If you're having these same issues I'd certainly recommend taking a shot at the MAF yourself. It's very easy to get to and swaps out with a special screwdriver, the parts will be under $200.

Replying to: neustkg (Feb 02, 2008 10:56 am) Did you ever find the root of the problem with your Grand Prix? My girlfriend is having the same exact problem with hers and of course the shop can't find what is wrong because it is not doing it while they have it. What makes it more frustrating for me right now is that she is not near my location so i just can't go down and help her whenever I like. So your experience may help me more rapidly answer the problem in a shorter amount of time. Thank You.
