A little help please.... My 2000 Grand Prix GT (3.8L non-super charged) just today started acting up. It will idle just fine, and then suddenly start missing, the rpm's drop, and then the engine either stalls, or just before it stalls the engine revs up to about 2000rpm and then smooths out to a nice idle again. Then it starts doing it all over again.
When it dies, it starts right back up again without a problem. I've tried it with the engine warm and cold and it doesn't make a difference.
When driving from a stop, it hesitates and either stalls or drives normal.
The car first started doing this today, my wife let me know when she got home, so I took it out and it ran fine, then she took it out and it stalled. I tried it again and it hesitated from a stop and bucked. I gave it full throttle and it lacked power and then took off like normal. On the next stop start, I nailed the throttle again and the car took off great. On the next one, it bucked again. I parked it and let it idle, and all was fine for a few minutes, and then the rpm's dropped and the car stalled.
Anyone here have an idea what it might be? I'm taking it in next week, but I'd like a heads up on what it could be.
