Thanks for your reply! TPS has been replaced as well as the coil/cap/rotor/wires have been checked as well as replaced as needed. I am also in my second year. Engine has been rebuilt, and the only problem with that was a stuck exhaust valve which I have repaired.

Comanche was bought knowing it had not ran in years, but felt like tackling this project. Always wanted a Comanche of my own. I will list everything I have done to the truck... in hopes someone can see something I might have missed. I am open to suggestion everyone :) 1989 Jeep Comanche 4 L 4WD Automatic - ECU replaced -TBS replaced -Idle speed control replaced -Oxygen Knox sensor replaced -temperature control sensor replaced -ignition replaced -starter relay replaced -fuel injector replaced -fuel rail rebuilt -fuel pump/filer replaced -spark plugs replaced -vacuum leaks sealed -electrical connections checked -neutral safety switch replaced Here is what the truck is currently doing. As a side note, it took me 2 years to get to this point... to actually get the truck to start. The idle is off. Either it is running way too high, or other times it is low and stalling out. Does not want to accelerate. Acts like maybe the fuel/air mix is not right? Possible timing advance not right (checked the sensors). I have not checked the sensors from the transmission to the TCM at this point. Any and all advice would be much appreciated at this point. Thanks for reading, and looking forward to all ideas.
