I own a 07 commander, v8 2wd that has been giving me idleling problems going on 1 year. I bought it brand new and it has around 70k miles now. The maintenance has always been up to date by a local jeep & chrysler dealership. The problem i now have is that when the car is on park (and sometimes while driving) it will start idleling high and low. Ive noticed that it seems to happen more when the a/c is on but it does it any form. Ive had the computer updated about 4 times and the ignition switch has been replaced 3 times. I was told by them that this would take care of the problem but it hasnt. Can anyone please help?
