Jerk back

Does your fan belt slip? Any rattle, squeak or funny noise? Could it be you tps? Does you cel come on?


I knew I guy from Granite City when I was in the Army......John Bodi was his name.
 
Sounds like a bad DIS module. If you haven't done it recently, I'd also change plugs and wires because they can do that too. But the DIS is the biggest culprit for the stop-go effect that you are describing.
