Re: Newbei needs help please!
I had the same issue with my '00 grand 4.0, and i went through what is called "the list", which is crank sensor, tps, cam sensor, coil packs, super cleaned the throttle body and idle air control module (attached to the throttle body), and mine still shakes a little at idle. Each step made it a little better, but i haven't run a scan to see the fuel/air mix ratio. Maybe the map sensor or o2 sensors?
