ok, i have a strange one for ya guys. i was sitting at a red light and my car starting shaking but it wasnt missing or anything. i turned my radio down to listen for any abnormal sounds and it was just quiet. i poped the hood to check for a vacum leak, nothing there. im at a loss as to what it could be. it still has good acceleration, it shook goin up a steep hill but other than that it only shook at the light. any thoughts?
