Jeep cough? Im lost..

I have no idea what could be causing this problem, Ill do the best I can to explain it.

Sometimes my jeep will have a hard time keeping speed, a very hard time. This has only happened to me 2 or 3 times. Ill be driving and all of a sudden it can't keep rpms up. I have to ease off on the gas or else it will stall. Its done this after wheeling or after mid-long drives. witch means it might have to be something about tempeture, but I'm not over heating or anywhere near that. sometimes its around 2.5k rpms but other times it will be around 1.5k rpms. Generally speaking it never dose this but when it dose I can barley keep speed while driving. its almost like I have water in my engine, but I don't. There is a jeep mechanic shop i could go to but like i said, it only dose this every so often. I couldn't show him what its doing.

Could this be a vacuume leak of some sort?
do my gears need to be re oiled?
is it something electronic?

Thanks JF!

For starters, check for any stored codes. The check engine light may not have lit up yet because the problem hasn't occurred enough times.

One thing that comes to mind though is that the bogging could be a busted up catalytic converter. A chunk could be rattling around and randomly plugging/unplugging the exhaust.

If you plan on driving it on the road as a street registered vehicle, Federal emissions laws require a cat. In general, having the cat will give you extra backpressure which will give you better low end torque, as well as cleaner air. It's better IMO to just get a cheap replacement (that is, don't get one from a dealership) if you find that the cat is busted up inside.

FYI - Talk of skirting Federal emissions laws regarding catalytic converters is not much tolerated here on JeepForum.

Well I asked the local YJ junkies in my club and they suggested it has to be something in the ignition or fuel related. I replaced my spark plugs and wires, next is the fuel filter..

Im sure that if i were to mess with the cat conv i would just purchase a new one. i know flomaster makes an aftermarket one. like i said i was just asking.. I don't want JF to hate me
