  1. Wild Comanche
    Hey Members, I'm new to Comanche Club and have a problem I haven't figured out yet. I have a 1989 Jeep Comanche Pioneer with a 4.0l and 4-sp automatic. I have done a conversion using a 1992 block and head. I have kept the Renix computer system, with a 1999 intake and 1996 throttle body bored to 60mm, Clifford exhaust headers with a Flowmaster muffler. 4-hole injectors rated at 21.5/lbs per hour. I'm getting 45 PSI of fuel pressure in the fuel rail. The engine starts and idles good. But has very poor acceleration. I have used the HESCO throttle body adapter for the newer throttle body. Did the 1989 Comanche 4.0l with an auto 4-spd. transmission have 2 throttle position sensors? I have one male 3-wire plug that I haven't found a female plug to fit. Any help will be appreciated.
