1989 Cherokee 4.0 Barely runs
Ok, so I have searched the forums for days now. I have found similar problems but not exact as mine. my problem is my Jeep is barely running, it pops, backfires, spits, sputters, backfires through intake, well yeah thats about it. I purchased it 4 days ago, so far I have tried 2 different ignition control modules, cleaned intake, cleaned throttle pos sensor, cleaned IAC, replaced spark plugs, all have had absolutely no positive changes in the idle, or rev. I know the timing is non adjustable, but I didnt know that before and attempted to twist the distributor to adjust the timing. call me crazy but it did change it. it made is so the thing would idle but still any throttle at all it would fall flat on its face, and pop backfire and sputter. since then if I start it again it will not idle correctly again. tomorrow I am going to check fuel pressure, I also checked the resistance of the Crank Position Sensor it was within operating range. also the previous owner said it happened 1 month after the local mechanic shop replaced the clutch. when you try to start it now I believe they screwed something up in the clutch because it will make some nasty metal on metal noises out of the tranny/flywheel/starter. any help would be much appreciated!
