'89 XJ 4.0 auto with 166K miles
I have been lurking here for a while and have done many searches on this and have tried the following to solve this intermittent stalling problem. It may run for a couple days with no problems and then it may only run a couple minutes before stalling. Sometimes it will crank right back up and sometimes it won't crank for days. Anyway here is what has been checked or replaced so far:
Fuel pressure is steady between 32 and 37 psi
Cleaned fuel pump ballast resistor connectors
CPS has been changed 3 times (last time only took 15 minutes) and the last one was genuine MOPAR sensor.
Cleaned MAP sensor.
Replaced O2 sensor.
Replaced temp gauge and computer temp sensors.
Replaced cap and rotor.
Replaced coil.
Adjusted TPS.
What am I missing? I also had to replace a badly leaking rear main seal. Is it possible that the flex plate in the bell housing is so covered in "gunk" that the cps can't read it? I tried looking at it without actually removing the inspection plate and it didn't look that bad at all. This is the first XJ I have owned and it is driving me nuts.
Sorry so long and thanks for any help!
