    I think you are thinking of the idle screw. It shouldn't need any adjustment.

    I'm not familiar with the second screw. My BBK throttle body only has one. Do you have a picture of this second screw?

    Basically, the threaded bolt is for bigger idle speed adjustments, and the allen head job is for more fine tuning the idle -its not normally needed.

    That's great news! I encourage you to double check your TPS voltage because it can change after adjusting it.
