i need help. pls pls help with this. i have a 05 grand prix, base model V6. about every other time i start it after its been running for a little while, it turns over, but stalls, over and over and over and over and over. and when it does that, it will miss while im pressing the gas, UNTILL i restart it, in which then it starts like a new car. SOOOO weird. no dealers can figure it out because there is no check engine light on. its sooo annoyying i would pay what ever to get it fixed, if i new what i fix. maybe a sensor? PCM? fuel pressure sensor? or something else. please help. message me or repost. thankss soo much!
