I have a 1992 jeep cherokee 4.0 il6 auto trans that is not in the best of shape but it is still there. I have just recently replaced the motor with a junk yard motor and after i got everything done and bolted up i had replaced all 6 spark plugs wires coil distributor with button and cap plus the crank sensor and o2 sensor. So it ran for bout 2 weeks after with no problems and then all of a sudden one day on my hr drive back home i left work pretty hard and drove for bout 20 mins down the road at 45 50 and then started to pull into a gas station and it shut off and hasnt started since then and have replaced all the above parts after it shut down that day. I have been fighting with it for 2 weeks strait now and need some help figuring this problem out!!! any suggestions please help me its my daily driver!! It fires from the coil but not very fast with turning the motor over with a plug in coil wire it only fires 4 times for bout 30 secs on constant turning of the motor??? with the distributor set at number one cylinder on tdc with wires correct it still back fires and shoots flames out the exhaust!
