Throttle Body: Adjustments

NOTE: The throttle stop screw is not used to adjust idle speed, it is used primarily to keep the throttle plate from sticking in its bore. Adjust only if the setting has been tampered with and is suspected of improper adjustment.
1. Use a screwdriver to back off the throttle stop screw (you may need to loosen a locking nut) until there is clearance between the screw and the throttle valve lever.
2. Use a small piece of paper as a feeler gauge and adjust the screw until it lightly contacts the paper.
3. From this position, turn the screw in 1/2 turn, and lock it down.
