Ever since I've had my car I've noticed a "skip" or "stutter" at idle. I was told that these cars just did that and didnt give it any more thought. Yesterday I was riding with VegasSRT4 and his car didnt have this problem at all. I checked my spark plugs to see if they were any carbon deposits or anything like that, nothing they look great. Does anyone know what might be causing this problem and is it something to worry about?
