2000 Jeep Cherokee Sport 4.0L Poor Idle Quality, Misfire
Posted to Chrysler Driveability on 10/2/2006 6 Replies

I need some help, this truck idles poorly and stalls out alot, it always restarts. The idle vacuum is about 16 inches and unsteady as if it has a bad valve. I did a leak down test and had no leakage on any cylinder, compression tests had 140 on all 6 cylinders...
