I got a CEL on my 99 4.0 the other day, for a misfire in cyl #4. Since then I have replaced the plugs, wires, cap, rotor, & CPS.
Jeep drives great at speed, but I can still feel it idling funny. The rpms dont really change but you can feel that its not running smooth.
I tested the resistance in the fuel injectors, they were all the same I think around 14 or so.
I am going to compression test tomorrow, but this jeep has 35k on it Id be pissed if that was the case....
I put some snake oil injector cleaner in this afternoon, and cleared the cel, see what happens tomorrow....
jeep in the middle....jeeps on the left has a trashed pinion bearing & the one on the right has broke a/c, so its been a heck of a week.
