Vehicle has been to dealer 5 times now for very rough idle, engine sag, idle undershoot, etc. PCM has been reprogrammed with current software, etc. Dealer called Chrysler and was told no fix is available for this condition. Vehicle shakes and tries to die. Very unsafe to drive as may die when trying to pull out. Dealer basically says Chrysler knows of the problem but won't fix it properly.

Intermittent engine idle problem. Occurs when engine is fully warmed up and in gear and at a full stop. Engine idle speed will fluctuate between 300 & 600 RPM. When this happens, engine roughness is very noticable and on occassion it will stall. On the first visit to the dealer, the computer was reprogrammed as per a tsb. This did not solve the problem. Second visit, Chrysler advised the dealer to replace throttle position sensor. Again the problem still exists. The dealer has notified Chrysler and is still waiting for an answer.

Dealer examined and replaced the control unit twice. No help. Idle speed is too low (400mph)! I want Jeep to do something. It's a lemon!
