Just wondering if all of these codes come up from the MIL eliminators not working correctly?
That sounds like you pinched a wiring harness (or corrupted the circuit) for the O2 sensors. Improperly made/installed MIL Eliminators may be causing it but I would double-check all the wiring first. Especially the wiring for the front (bank 2) O2 sensors.
