I have since figured out that 2-3-1 is defined as:
LAMBDA ADJUSTMENT; FOR 1994 AND LATER, HEATED OXYGEN SENSOR (MIXTURE TOO LEAN UNDER PART THROTTLE)/ LONG TERM FUEL MIXTURE TOO RICH IN PART LOAD STAGE.

After all that, I am going to assume that one or more of my o2 sensors are bad.
How do I know which one to replace?
