Ive only had my grand prix for about two months, has 82k miles. Im wondering what the problem could be .. cause it only does it once every couple days or even every couple weeks, and if I turn the car off, then back on again the problem stops. When this is happening and I accelerate from a complete stop or near a complete stop, as I accelerate it feels real sluggish, and even jumpy if that makes sense. No check engine lights have come on and like I said, if i restart it goes away until next time. I have read a couple other people having the same problems and it just being an '05 glitch .. but I hate this and want to fix it ... but dont want to pay hundreds trying to figure out what it could be. Anyone have any ideas or similar problems?? Thanks!
