When Im at a redlight, I feel a very slight shake. The RPM needle maybe moves up 100 when it shakes. Car runs fine. Was just wondering if thats normal. I had some work done over the summer, exhaust leak, oil leak burnt some wires. replaced it all. I just dont remember how the car used to be before all those issues

 

Mine does it sometimes but a stock car in good mechanical shape should run pretty smooth.
