Question now is, how do I get my stop screw in an optimal position?
Let the car idle till it is at normal temp, 3/8 on the gauge 96 and newer models or 1/2 on 95 and older. Then slowly block the IAC port and adjust screw to hold 450->550RPM when the port is fully blocked off. While blocking it off if the car drops down too low turn the screw to open the throttle plate a bit. If it slowly dies but is trying to run at 500+/- that is OK also. With good plugs it will usually idle right down to 500 and not stall out with no problem though. The throttle body will be hot so be sure that you have a big chunk of leather belt to block the port with. Do not try tape or paper as it will end up in the engine. Piece of old leather belt will not get sucked in and will keep you from burning your finger.

REWARD EXCELLENCE!
