The sensor at the rear of the cat may have intermittant failure.

The wiring to that sensor may have a problem.

The PCM may have a problem.

the computer was dealer replaced in july. during the same time, the temp sensor was replaced,
and a cracked solder joint repaired on the circuit board of the gauge pod.

Do a visual inspection of the O2 sensor harnesses.

Use a scanner to view live datastream O2 sensor activity.
