The car would jurk In up hill climb at first, then it got regular in driving. the engine is running very rough I have replaced the wring since found the #2 bad. I have checked the control mod and the coils.

Knock sensor-- maybe
Cam sensor-- maybe

I had the service done at 100,000 miles.

Rough idle can be a vacuum leak, a bad PCV valve, a bad EGR

On the main page of this site, go down and find tech info, then click on testing. I have a write up in there on testing the EGR solenoid. The only other test is a visual inspectin of the EGR tube for cracks.
