My 1993 wrangler 4.0 liter. Starts and runs great. Then somewhere in the warm up cycle runs like it is way out of time.. then after a complete warm up runs great? I have replaced every sensor on this jeep O2, cps, cam position sensor, map sensor, coolant temp sensor, had the pcm rebuilt, new pkugs wires,cap rotor... what am I missing? Please help! I love my jeep want to get her on the road!!
