Sharp jolt after shut off - 12/4/2007 1:38:40 PM    Xtreme Blizz Posts: 71 Joined: 7/13/2007 Status: offline For the last few days when I turn the key to shut off the motor I feel a shake in the car almost like if i lifted the clutch while the car was running and it stalled. I have started and shut off the car while on a lift and don't see it hit anything but it shake for about 3 seconds and then shuts down. anyone with a answer Post #: 1
