problems with a rough idle.? At firs the car was starting rough too. 2 tanks of gas in a row I added fuel injector cleaner,(STP). The rough start went away completely. The rough idle did for a month or 2 but, now it's back. When I'm idling at a stop light or something the car shakes a little and the RPM gauge moves back and forth a little. I'm getting ready to go pick up another bottle of fuel injector cleaner but, is there a problem that I need to have checked out?
Thanks!
Thanks!
