Well I have two rigs down so I go grab the other 91 XJ.

All the way home it misses,bucks,spark knocks,etc.
Hot Cold it doesn't matter and sometimes it shuts down when to push the clutch in to down gear at a yield or stop light
For the past 6 months it will run great then for no apprent reason it runs like a dog.

I have changed Plugs,Wires,Coil,Cap/Rotor it runs fine then back to the above problem.

It has a 4.0 with a AX-15

CPS?? Oxygen Sensor?? Injectors?? Dizzy ??
I don't want to replace a bunch $$ of parts but I need this Jeep to run better.

So any ideas........
