Big Screw on throttle body. Idle Adjustment?
What is the flathead screw on the throttle body on the 3.0? It sits right next to the intake chamber and throttle body. I can't really find any info on it.

Well if it's the one I'm thinking of (it points towards the rad) then it's the idle speed screw, it's abot 3/8"-1/2" in diameter. Clockwise slows idle, counter clockwise increases idle.
