You have removed the main cat and it may be that the secondary cats just are not up to the job of getting the numbers right. We did just the opposite, and removed the secondary cats and the pipes had a bung for the 02 sensors. All works well and the Durametric shows all normal operation and readings.

This confuses me. Someone correct me if I'm wrong, but the 02 sensors are only before and after the
upstream cat, right? If you eliminated the downstream cat (what you refer to as the secondary cat--the ones back by the muffler, right?), why would you change anything with the 02 sensors?
I haven't had a chance yet to read the Mike Focke link you sent (thanks for that). I will...maybe that'll make it clear.
