those have a brass rod at the end of the throttle cable that opens and close air flow. those brass rods sometimes wear especially on stangs because owner are jumping on the gas pedal all the time. Make sure throttle linake and cable are lubricated well, also make sure return spring is at proper tension

Suggested Repair

Inspect the brass rod at the end of the throttle cable for wear, lubricate the throttle linkage and cable, and confirm the return spring has proper tension.

Conversation Summary

The owner reports a Ford idling at about 2000 rpm. Adjusting the idle screw did not help, and they asked whether a vacuum leak or a faulty IAC, EGR, or PCV could be responsible. The expert advised checking the throttle-cable brass rod for wear, lubricating the throttle linkage and cable, and verifying return-spring tension.
