Well if you look back to around 7/4 you'll see that I was having problems where my engine would just stop running. Sometimes it would start right away some times over night. No warning. Everything pointed to the CPS. It was replaced but the engine has never run smooth. Keeps missing except when excellerating although it HAS NOT QUIT Running.
It's a 95YJ-4.0 auto. Has lot's of power. If I reinstall the faulty CPS the engine runs beautifully until it quits. There seems to be several CPS for this engine. The OEM part had #311808 (31808). According everything I can find that is a CPS for a 4.0 standard Trans. My Jeep is auto. I purchased the CPS recommended for Auto Trans. Have checked VIN #'s etc. Everything shows this YJ has always been auto. The part that replaces the OEM # also seems to have 2 ears for fastening to the bell housing. The OEM that came out and the new ones all have one on the drivers side looking forward from under.
Purchased another CPS model and mfg. Runs a little smoother but not good. Does the computer need to be reset for a new CPS installation? Any other ideas?
