loosing power

I am new to this site and after reading some of the posts I thought I would give it a shot.

I have a 94 Wrangler - just over a 100k and am having some issues on power. On the highway - typically after 40mph the jeep looses power - almost like a hiccup and if I put the petal down there is NO pick up. It comes and goes.

I just put in a new oxygen sensor, cat, plugs, the header has been welded and is in good condition, and a new exhaust.
I have also used some dry gas the last few times and put in premium gas...

I am out of ideas. Any suggestions would be great.

Your catalytic converter might be starting to clog.

I would imagine that dry gas = fuel additive, cleaner, gets rid of any water in the system, treatment. Like Barrymans, or the like. Is your 94 Wrangler fuel injected? If so, you may have some clogged injectors. I know you said you tried "dry gas", but have you run Barrymans fuel treatment? It will usually clean your injectors very well, if carburated, shoot some down the carb, it will clean it up real well. If you have an in-line fuel filter,which I am sure you do, try replacing that.

Also might want to look at the condition of your coils, distributor cap and air filter. I had the same problem on my 94' wrangler i purchased in january, Did a full tune-up, found oil on my air filter, replaced the pcv valves that run from the valves to the air filter box, and now my jeep runs strong as can be.
