To adjust the idle on a 1994 Hyundai Excel, first ensure the engine is warm. Locate the idle adjustment screw on the throttle body; it may be covered by a plastic cap. Turn the screw clockwise to increase the idle speed and counterclockwise to decrease it, checking the RPM with a tachometer as you adjust. After adjustments, let the engine run for a few minutes to stabilize the idle speed before finalizing the setting.

How do you adjust idle air control Hyundai excel?

To adjust the idle air control (IAC) on a Hyundai Excel, first ensure the engine is at operating temperature and then disconnect the IAC connector. Use a multimeter to check the resistance of the IAC valve, and if it's out of spec, replace it. If adjustments are needed, you can turn the idle speed adjustment screw slightly while monitoring the idle RPM to achieve the desired idle speed, typically around 700-900 RPM. Always reconnect the IAC connector and recheck the idle after any adjustments.

You don't. The ECM (Engine Control Module) maintains the correct idle speed. If the idle is out of control you probably have a vacuum leak.
