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.
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.
For a 1994 Hyundai Excel GL, the ignition timing should typically be set around 10 degrees BTDC (before top dead center) at idle. To properly set the ignition timing, connect a timing light and ensure the engine is warmed up, then adjust the distributor as needed. Always refer to the vehicle's service manual for specific details, as variations may exist based on engine type or modifications.
it seems there a small screw back of the intake but the idle is control by the ecu.

How do I adjust the idle on a 1994 Dodge Caravan?
Computer controlled - not adjustable
the TPS (throttle position sensor) controls the idle.
Hey JustinThe idle speed is controled by the ecm and is not adjustable. Goodluck, Joe You can adjust the idle air screw. Get a haynes manual it will show you how
May be computer controlled and not adjustable
You can't adjust it, you have to replace either the IAC ( idle air control ) sensor or the TPS ( throttle position sensor ) to fix a bad idle.
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.
Idle speed is not adjustable.
