1994 yj acceleration problems

I have a 94 wrangler yj with aprox 182xxx miles and when I drive down the road my jeep starts to sputter and bog like if it's not getting fuel butt if i take it out of gear and rev the engine it's fine. Its at the point were I cant go over 10mph if you guys have a solution that would be great.

Parts changed in the last 2 months
Co2 sensor
Fuel filter
Crank sensor
Regular tuneup
map sensor

Sounds like the problem that i was having with my 87. It ened up being a clogged cat. Replaced everything like you did(except mine is carbureted) and finally figured it out when the clogged cat blew apart and removed the muffler off the back of it...lol.

Try unbolting the cat at the flange, and taking it for a ride. Its a little loud but it will tell you right away if that is your problem.
