My Guess is that my bank 2 injectors were running rich, burning out my cat and also attributing to these codes. Once I replace my injectors, the codes were resolved.
Interesting, so did you replace all 6 injectors?
Edit: did you log when you were having issues? Was there a difference in trims or AFRs between the two banks?
