The operator said it failed because of Catalyst - not ready, Evap - not ready, and O2 Sens Htr - not ready.
This is the first time it has failed, but has the same mods as all previous OBD-II inpections, which it passed.
Any ideas? Could it be the rear O2 sensors need replacing, or do I need rear O2 simulators?
