You can't adjust the idle , There is a minimum idle adjustment set at the factory , you don't want to mess with that . The PCM / ECM ,engine computer controls the idle speed by the idle air control valve (motor) . You may have a dirty throttle plate mess with the base idle .Check out this video on ford base idle adjustment . Some one who didn't know cranked up the base idle causing problems Ford IAC valve test how to adjust minimum idle speed

Its not really adjustable.
The computer controls idle speed via the idle air control valve.
You probably have a vac leak.

you can adjust the idle air right at the air intake

adjusting idle will be a big mistake,,,,tps ,trottle plate, map will be misadjust too.
Idle is set by iac valve. you have to find out what cause idle to change.

are you allowing the car to warm up first before checking your adjustment screws? have you also checked the timing of your vehicle?

It should have a base idle adjustment and could also have an idle speed control motor.
The base idle screw should be on the driver's side of the carb. You would also have a fast idle screw on the choke.

First, you shouldn't adjust the idle. If the idle isn't correct, that means there is an issue somewhere - not that the idle needs to be adjusted.

There isn't an adjustment screw. To adjust the idle, you will need to move the TPS (Throttle Position Sensor) forwards or backward. To do this, you will need to remove the tamper proof bolt and replace it with one that can be loosened and tightened.

the idle isn't adjustable. you might want to have the idle air control motor checked out. they are prone to sticking in the open position allowing more air into the intake
