Removing the sensors will have an effect, and the engine will run poorly or not at all. If you staight pipe after the cat converter and leave the sensors, you will probably be ok. There are o2 sensor simulators available aftermarket, though I dont have experience with them. Removing the cat may cause problems with emmissions inspections as well. If you do remove the sensors, and it runs ok, you will probably lose gas mileage and power, because the computer will get confused.
All the O2 sensors are threaded into the exhaust system at various points.
There are a couple of reasons why a Jeep Wrangler may be sputtering. There could be a problem with the sensors or a problem with the fuel lines.
The throttle position sensor is a potentiometer.
You can not eliminate the oxygen sensors if you ever want the engine to run properly.
Two, one before the cat and one after.

It does not have CO2 sensors. It has O2 sensors, four in total. One before and one after the catalyst on each side of the engine.
Your engine will have 4 O2 sensors. And all of them will have a different part #, because the connectors are all different.
Two, one on each side of the catalytic converter.
The 2001 does not have a coolant sensor port in the head like the 1992. All sensors and wiring are different.
If the oxygen sensors for the 1991 Chevy 4.3 is running rich when it is warmed up it is best to have the sensors replaced. Once the sensors are replaced this should resolve the issue.
A lot of things, but start with the distributor, and cam/crank sensors, then try the coil
