alright i did a head gasket, lifters, and push rod on my jeep since i was losing a gallon of coolent every week or so.teh tear down ran smoothly. then putting it back to gether ran the same way i broke nothing and lost parts. now here is my problem:
the engine will start and idle for mayb 1-2 secs at reg RPMS then it will just rev to 3000-5000 rpms orwhenever iturn the key off. this does it all by it self no one touching the gas or opening the throttle body.i have replaces teh TPS censor the IAS teh fuel pressure regulator on the fuel rail.i cleaned the TB off the jeep with both the TPS and IAS off of it. iv been trouble shooting this for a week and icant not figure it out. i called jeep and they said it sounds like an electrical problem not mechanical. any input would be highly appreciated i just want my jeep back lol thank you
the jeep is a 1991 cherokee 4.0 HO with auto tranny
