I have a 2001 Cherokee sport with the 4.0 4x4 and it has a random misfire causing it to run like absolute shit.
Process of elimination has begun and I have no clue what it could be at this point. So to start I’ll list everything I have tried and see if anyone has suggestions
1. Compression tested all between145-155
2. Fuel pressure checked consistent at 50-55 driving or idling
3. New plugs
4. New coil pack
5. New crank sensor
6. New cam sensor and synchronizer
7. New map sensor
8. New pcm ( flashed correctly)
9. New engine harness(replaced yesterday off same exact vehicle)
10. New o2 sensors (all4)
I have been trying to figure this out for quite some time and am getting to my wits end any advice would be greatly appreciated
