DoubleAIm ,YVR. i am at YXX, i would look at repairing the secondary air pump, at least that would permanently rid you of the CEL. Does your scanner give a "readiness indicator"? I know that there needs to be a certain drive pattern done before all sensors are on line and your readiness is good. If youre near YXX give me a PM and i could have a look with my scanner, and see if there is anything amiss!
