Ok, so right now I am running catless in my Stage 2 ss/sc. I have not had the 2ND O2 sensor shut off because I plann on getting a new header DP combo. I bought a OBD II code scanner to shut off my CEL, when the other day I got a P1133 code, but my book doesnt list it? Any one have a clue what it is?



Thanks,
Matt
