1. Classic signs of a clogged (or clogging) Catalytic Converter.
2. Have the exhaust back pressure checked,
3. Any exhaust/muffler shop can do it for you.

I had a 95, similar symptoms turned out to be the cac had come apart and the bulk of it clogged up the muffler. It was a 150.00$ fix, but I never had power issues again.

Re: 1992 Jeeep Wrangler No Power

I took the catalitic converter and look inside all the stuff inside come apart all is left is two pieces. It seem I don't see any clogging I can see thru and looks like a straight thru pipe. Where could be the clogging is at the muffler? I'm still confuse, do you need back pressure and the catalitic converter providing he pressure? I'll try to test drive it without muffler and cac attach to it and see if I gain the power back.

Any advice are appreciated.

1. It may be easier to...
2. Pull out the O2 sensor for a few minutes,
3. That removes the back pressure,
4. And preserves your neighbors sensibilities.
