    Default Car is throwing a P1133 Code any1 know how to fix this

    My gm846 cammed formula is tossing this code up every time I drive it. I scanned it and it said it was an air/fuel ratio issue. My car retains all stock and legal emissions components and other than the cam, full exhaust, and full bolt-ons it remains stock internally.

    Is this something a tune could fix? Or what sensor has failed and caused this shitty situation? Car does seem to be slightly down in power, but still hauls faster than it did prior to the cam install. Thanks Guys
