Hey all. 94 XJ 4.0 auto. Awhile back I posted about some running problems that I thought I had figured out. Right now, it is idling pretty rough. Really really lopey. And I can hear what sounds like a misfire from the exhaust. But it really just sounds like it has a bigger cam. It runs well for the most part. No smoke, not much if any hesitation. Just last week I replaced the following. Exhaust manifold (due to crack), cat, muffler, plugs, wires, cap/rotor, air filter, O2 sensor, fuel filter, fuel injector o-rings, and did a good cleaning on the intake and throttle body while it was off. And I was careful not to mess up the sensors on the TB which are pretty new.
So I guess I only have a few easy fixes left. could the CPS be making it idle bad? Since I cant mess with the timing... How about the distributor pick up or the distributor itself? Could it need a new MAP after almost a year? Let me know if you come up with any ideas.
