I have seen muffler baffles get loose and plug the exhaust it can happen also.

Unfortunately it drove in the same exact way when I took the O2 sensor out. It sounded awesome though.
Also forgot to mention I have an aftermarket muffler and the resonator was deleted.

The cat could be an issue but i'm not so sure now. Nevertheless i'll replace it soon because it's the original -- and very rusty.

Could something be up with the transmission? It only stumbles/hesitates most noticeably when it goes right into 3rd gear.

I'd go back to verifying a good ignition system and checking the carb. Before adjusting anything on the carb verify the correct TPS base setting and voltage output through the entire range of travel. Mixture control, timing advance, and TCC lockup depend upon that being correct, as well as the EVAP purge and a few other items of lesser significance. After verifying the TPS and correcting it if necessary, check the lean and rich stops and set the MC solenoid mid position.

It may also be beneficial to verify the correct TV cable adjustment if in fact the trans is actually a 700-R4.
