Found a jeep on Craigslist.
99 XJ/4.0/AW4
200k miles.
It has a really bad misfire. Pulled 9 engine codes. 2 or 3 related to 02 sensors and the rest are multiple cylinder misfire, cylinder 5, cylinder 4, etc misfire. I've never seen a 4.0 idle as rough as this one.
Do you guys follow my logic?
- Check for crossed plug wires then replace; Plugs, wires, cap, rotor, and the coil.
Going to do a compression test as well before I purchase it.
