After I Drive the jeep for a few min. I Can park the jeep and leave the engine running and it will idle at about 1000 RPM with no Problems. Also almost every time I start the jeep with out my foot on the gas the RMP's Go Straight up to 2000-2100 then they drop down quickly to about 800-1000 After the jeep is warm it will idle in park at about 1000-1100 RPM's

I Know I am thinking it may be a Vacuum Leak or something. This problem is driving me crazy. I guess I am going to have to put the jeep in the shop. I don't know what else to do. I have been trying to figure this out for almost 2 weeks now....

have you disconnected the battery since changing thing some say the ecm needs to relearn values of new sensors ,vacuum leaks are easy to fing carb cleaner and spray around throttle body and intake manifold listen for changes in idle
