Most common problems with 4.0L and 4.7L jeeps. From my experience owning two WJ jeeps. 1. Oil leaks from rear main seals, valve covers and oil pan. High mileage oil seems to help.

But indeed you should have a check engine light with a P030- code (- = cylinder number) or P0300 for multiple cylinder misfire.
