08 wrx stage 2. throwing codes
hey guys- I have a 08 WRX. I have cobb intake, Turbo XS TB exhaust and cobb V3

Im on stage 2 91+

And I have been getting a couple codes, and wondering what would be causing them, If I delete the codes they go away, but they eventually come back a couple days later

codes that I have been getting

- P0420 catalyst system efficiency below threshold (bank 1)
- P2096 post catalyst fuel trim system too lean bank 1
- P0137 o2 sensor circuit low voltage (bank sensor 2)

I've had the first 2 codes many times and the last code just once.

I sent my datalog to cobb, and they said everything looked good.

Do i just delete the codes, or is there something I should fix?

Does the TB have cats? If not and there is a spacer on there (the 02 sensor mechanical fix for being catless) it could be spaced out too far, or your 02 sensor might just be bad.

there is no spacer on there.

Your sensor is probably bad.
