There is none. It is electronic. Try replacing the idle motor.
it is the large screw with a temperature check pod on it right above the throttle spring
Idle speed is set by the PCM and is not adjustable. The screw you are fiddling with is just the stop screw to adjust the initial throttle plate position, it should not be used to attempt to adjust the idle.

Most likely a bad idle control (also called IAC or ISC). Otherwise, it it also seems to run rough, consider the possibility that it might be overdue for a tune-up.
its located on the throttle body
between 500/750 depends on where the idle screw is set
Don't mess with that adjustment. The idle speed is electronically controlled.
The idle adjustment screw of the idle control valve is what needs adjusting. Either opening or closing the valve moves the throttle plate and adjusts the idle.
Theres a screw on the Throttle body at the end of the intake manifold. turn it with a screw driver left or right.
Set idle speed to proper r.p.m, by adjusting the IDLE SPEED SCREW. Turn the IDLE MIXTURE SCREW or the AIR SCREW to for correct procedure, achieve highest speed and best response. The IDLE MIXTURE SCREW (FCR) controls fuel delivery to the idle port and the SCREW is located on the engine side of the carburetor slide. Turning the IDLE MIXTURE SCREW out will make idle and off-idle richer. Turning IDLE MIXTURE SCREW (CR, PWK, PJ, PE) controls the amount of air to the IDLE and SLOW CIRCUIT. This SCREW is located on the air cleaner side of the throttle slide and turning the SCREW out will lean the mixture and turning the SCREW in (clockwise) will richen the mixture.
Idle is computer controlled, no adjustment screw.Idle is computer controlled, no adjustment screw.
