02 ss ck engine light after headers, pcm reprogram
My 02 Camaro ss has ck eng. light on with front 02s insufficient switching, after I installed headers, and reprogrammed the ecu. I already installed new Bosh, and GM O2s; by the way the Bosh switches more than the GM O2s. Has anyone had this problem before. I dont have any other mods other than ported TB, and modified air intake. By the way it runs great when the light is not on.
