I have 250K and facing oil consumption problem as well, my check engine light would come on and off after several hundred miles then on again. I had the codes P0420 (catalyst system efficiency below threshold bank 1) and P2103 (throttle actuator control motor circuit high), i tried BG EPR/MOA didn't see much change. Thinking of maybe doing it again??? I'm thinking of maybe just the O2 sensor or do i need really to replace my cat converter. We don't have hybrid service shops around my city(very rural) except to go to toyota which is very expensive. Thank you for any help.
