Friend of mine is working on a 95 Cherokee Sport 4.0L, automatic. When he got the Jeep, it would not run. He replaced the crank sensor and it now runs, but lopes badly at idle and backfires thru the throttle body and exhaust when revved up. Very sluggish pick-up.
He has replaced the crank sensor with 2 new ones from O'reilly (BWD brand), the MAP sensor, the temp sensor, the coil, plugs and wires, the entire distributor with cam sensor, and the computer. No change in symptoms.
Once in about every 30 starts it will run and drive perfectly. The vacuum is good, and the fuel pressure is at 39 lbs. He has seen the timing change by 30 degrees when revving it.
I advised him to go and get a different brand of crank sensor, but other than that, i am out of ideas. Anyone care to chime in with an opinion? Any and all ideas appreciated.
