I'm going to have the dealer check it out. The car only has 1,000 miles and the '04 has about 4,200 miles. Like i said it's smooth and revs smoothly its just when you come to the light or a stop sign the car just starts idling roughly to the point where you can see it in the rpm gage slowly moving up and down so i know this is not normal. I'm gonna have it checked out today.
