Changed all plugs, wires, cap n rotor, changed the 1st plug a second time and still a misfire ? Jeep still rinds and drivable doesn't bog-out almost like its a late fire but still need to fix this problem if any one has any input or similar problem that they fixed, some feed back would be great

 

Do a compression test and make sure it's not a mechanical issue.

 

Forgot about that, thanks brother

 

You can also swap the injector to another cylinder to see if the misfire moves.

 

I am having the exact same problem. I hope to learn something from this thread
