I got a check in light today when i started up my car, drove down to advanced and ran it for codes... the guy told me it was an o2 sensor bank 2? Im not really sure if hes talking about the rear o2 or what... the only time i got a check engine light was when i put on my CAI.. i replaced the IAT sensor and reset the computer and the light went away.

The only current symptoms ive noticed are:

1. Kinda rough idle while in park.
2. gas millage is crap.

Im thinking the gas mixture is not right so maybe its setting off an o2 code.? (due to the Cai maybe..?)

Im kinda debating on just putting the old stock air intake back on.... not really sure..

Could an (o2 bank2) code possible be that IAT sensor i replaced about 1000 miles ago?

any help would be greatly appreciated.
