1) probably your tps (throttle position sensor)
2) could be a loose hanger on your exhaust

check your vaccum lines for holes, loose connections or even a collapsed line. any thing of that sort will cause odd idling but the car will still run ok had a similar problem a while back and it was a collapsed line

Have you done anything to it recently?
When you are accelerating is it just the exhaust that rattles or the whole car/engine shakes? Is the check engine light on? Definitely check all hoses under the hood and all connectors (sensors/coils). |
