87 Wrangler 2.5 no lift. Starts Cold great. When she gets hot , bogs down going up hill , backfires and almost dies. In the shop right now and they have checked catalytic converter, OK.
compression OK. Vacumn OK. Spark OK, Fuel Pressure OK.
I have replaced the computer last Month, has a new EGR, Oxygen
sensor, Fuel injector o-rings, MAP sensor, MAT sensor Etc, etc.
Good Shop , they are going to have the electrical tech look at it

ON THE PROBLEM.

There was an 88 and an 89 that had the same problem up here a couple of years ago. Unfourtunately the cause was a completely clogged cat. converter (which it sounds like you allready checked). I'd make sure they had a GOOD look at the cat and see what the airflow through it is like. I hope all goes well.

fuel pump? getting warm and slowing down Had one that fuel pressure cold or idling warm was ok but under load it would drop and bog.
