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?
