This is computer controlled
adjust the idle screw on the drivers side of the throttle body turn it to the right to lower you idle turn to the left to raise it
Idle is computer controlled and can NOT be adjusted.
You probably can't. fuel injected cars have the idle set by the ecm.
The idle is control by the idle air control motor from outputs from the Engine Control Module.
There is no adjustment, the idle is controlled electronically. If you have idle problems you may have a vacuum leak somewhere.
In most 1990s and later vehicles you cannot adjust the idle. It is controlled by the ECM or computer. An idle that is not correct indicates something like a vaccuume leak or a sensor issue.
Ford stopped manufacturing the Falcon in 1970.
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.
The idle is controls ONLY by the PCM. Replace your ECTS along with cleaning the Idle Air Control valve located on the throttle body.
Why adjust idle... if this is a n/a you need to just leave it alone unless you have a consistent idle less than 900 or more that 1100 .... You will get no gain from this and if you don't have a consistent idle there is probably something else wrong.....
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.
You adjust idle with idle timing
