Good evening and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 18 years and I will do my best to help.

Is the check engine light on and of so what codes are showing? Have you checked the fuel psi?

Customer: replied 1 year ago.
The check engine light is on but no codes are showing and the fuel psi is fine. The problem only happens at idle and its intermittent. We also changed the coil pack but still having the same problem. The tach jumps on idle intermittently.

Thanks for the reply!!

If the check engine light is on you will need a scantool to retrieve the codes so you will know what the PCM is seeing wrong. It could be as simple as a sensor such as the crankshaft sensor but again we won't know until you retrieve the codes. Once you do post the codes here so I can better help you get it fixed..

Talk soon,

Thanks for your help the problem is solved. The crank sensor was loose. I would like to know what the factory idle setting is in park for the same jeep.
