O.k here we go. I have a 1990 jeep cherokee limited with the 4.0l six cylinder. I just put a brand new engine in the jeep yesterday and it fired up fine. The only issue of many is that when i go to give it throttle it spits, sputters and backfires. I have checked I swear alomost everything.
crank sensor
tps
map sensor
distributor cap/ rotor
plugs / wires
dampner hasn't spun on the rubber my tdc is perfect this engine was rebuilt by the manufacturer
I just barely pulled the tranny back out and pulled the flex plate thinking that I bent it or something putting the engine in. We did a run out on the flex plate the chilton manual say to not be in excess of .016 the one I pulled off had three spots on it that was low or out of round by .020 so I assumed that was the problem. The used one that I had laying around only had one spot that was kind of flat or out of round by .017 which is pretty close to .016 I think it might work.
Can anyone give me more ideas about what to check.
I have also pulled the keeper off of the dist. and stared the engine and when I retard it or turn counter clockwise it will pick up and run descent. The alignment hole on the dist. is covered up about half way with the tab
on the dist. aperwork
