No. You have other problems involving the induction, fuel pressure, or spark on the engine. If the check engine light hasn't come on, then a good place to start is with is the fuel and air filters. If they are good, then next would be plugs and wires. Also look for vacuum leaks. We had an 87 that ran terribly, replaced all the above, and found out that the MAP sensor was bad. No codes coming from the PCM. Frustrating, and time consuming.

Oxygen Sensor Circuit (Rich Exhaust). This may of may not be a defective O2 sensor. It may be something else that is effecting the O2 sensor. But considering the vehicle is 22 years old, I would suspect the O2 sensor needs replacing. I would replace the O2 sensor.
It would depend on the vehicle. most likely the vehicle would run, but not well. this puts the computer in limp home mode. most car computers will allow the vehicle to run with one major sensor undone.
I would test the temperature sensor first. Then have the car scanned.
A TPS is normally known as a "throttle positioning sensor" price would be dependant on the vehicle.
The bank 1 sensor 2 O2 sensor on that vehicle should be the sensor after the catalytic converter. Inspect the wiring for damage, cuts and such, if the wiring looks okay it is probably the heater circuit within the sensor, replace the sensor. Unplug the wire harness from the sensor and cut the wires off at the sensor. This will allow you to slip a 7/8" box wrench over the sensor to remove it. Install the new sensor using a 7/8" open end wrench, tighten it as you would a spark plug. Reconnect the wire harness.
