You can adjust the idle.
Turn the Idle Adjusting screw.
Idle on a 1985 Honda Civic is adjusted through a idle air control valve. This valve is located near the intake. Adjust the valve by either loosen or tightening it.
You cant. The idle is controlled by the ecu.
The idle speed is computer controlled
All Ford vehicles cannot adjust idle nor timing wich is pre-set at the factory and the computer sets the idle and timing, vehicles after 1990 no longer can be adjusted.
Most likely computer controlled and not adjustable
Ford stopped manufacturing the Falcon in 1970.
A bad IAC (Idle air control valve) or a vacuum leak or both.
Don't mess with that adjustment. The idle speed is electronically controlled.
