I am working on a 97 xj 4.0 auto and trying to track down why it has a miss in the engine. I know my way around an xj and this one has me stumped. I have replaced the following:
Plugs
wires
cap
rotor
TPS
IAC
MAP
CPS
CAM
ignition coil
injectors
computer
fuel pump
I have also taken off the valve cover to check for a stuck lifter and all is functioning properly, also the cat converter is not plugged either. I am stumped as to what the problem could be as I believe I have covered most of what could cause this problem. I also put a breaker bar on the crank to see if there was excessive play in the timing and there is no play. Any thoughts and suggestions are greatly appreciated, oh and it is not throwing any codes at all.
