    I dont remember seeing the air inj system on the list of Ready State tests, but that doesn't mean they aren't part of the complicated loop GM has setup in the routine.
    The rear o2's are.
    I believe in most states the RS tests all have to pass but two of them.
    I've heard they've increased the difficulty to one test now, not sure cause we dont have it here, so I dont keep up on it.

    Basically, if you delete anything in the PCM, it's not "legal" and shouldn't technically pass, but sometimes it does.

    Check to see if your county does the probe testing or just tests for SES lights and a visual.

    good luck,
