Some ideas:
Check the O2 sensor to assure that it's actually working. You can do this with a sufficiently accurate multimeter to see the signal/voltage that is being sent to the DME. The voltage from a correctly functioning sensor will vary back and forth as mixture varies. I don't remember the actual voltages. I think that it's from either -1 or 0 to +1v. Someone jump in here and correct me if I'm wrong here. A wave function/display on the meter is great for this.
When replacing the sensor, did you replace the sensor and harness both as a whole unit? Or did you splice the new sensor onto the existing harness? If you spliced, did you solder or crimp the connections?
Here's another possibility. The overly rich mixture could have ruined the catalytic converter over time. Anyone have any idea about this?
