Car has run flawless for 18k miles so far. I have borla uel headers, greddy axle back exhaust and Crawford billet power blocks with the OFT stg 2 tune. Today I had these two codes pop up. I believe they are something to do with the 02 sensor getting poor readings. I know my front o2 sensor is not seen by the ecu but could not having a cat throw off the reading of the second sensor? I'm in Canada so the temperature is starting to dip. This will be the first winter with catless headers. Anyone have done experience with this codes?
