    I know it has to do with the secondary AIR injection system and, I searched but no one had a fix for it. I was wondering if this is the little box where the stock air box was, and what the fix was to this problem, also if this would cause a misfire.
    EDIT: I have a misfire kinda like a bucking after I first hit boost after that I can not Push WOT with out it bucking and missing.

    I never figured it out either. I ended up blowing the motor with my turbo kit and took the car to the junkyard.
