Ok - 1992 Cherokee Sport 4.0L, auto, 110k miles.
Engine stalls and runs poorly AFTER heating up.
I can often get it to idle or run at just above idle just fine (that's how I got it home) but too much throttle and it keeps choking, then catching, then choking again. There's no place on the throttle range that runs well, which makes me *not* suspect the TPS - should I? If I floor it, it runs at low RPMs but sounds horrible (and no power).
I changed the fuel filter - no change. Since it runs fine until hot, I don't suspect the fuel pump - should I?
This begin occurring immediately after it sat for a few months while I was out of town, in a humid tropical environment. It's hell on cars here and I'm suspecting one of the sensors is out of whack but I don't know which one to look at first.
Oh, and the only ODB code is 1-2-5-5. Battery disconnected.
Any help is terribly appreciated!
