To adjust the idle on a 1992 Buick Regal GS, first locate the idle air control (IAC) valve, typically found on the throttle body. Start the engine and allow it to warm up to normal operating temperature. Then, adjust the idle speed by turning the IAC valve's adjustment screw while monitoring the engine's RPM; aim for the manufacturer's specified idle speed, usually around 600-800 RPM in gear. Always double-check your adjustment by letting the engine idle and ensuring it runs smoothly.
High idle when the engine is warm in a 1990 Mercedes SL 500 can be caused by several factors, including a malfunctioning idle air control valve (IAC), a vacuum leak in the intake system, or a faulty throttle position sensor (TPS). Additionally, issues with the engine management system, such as incorrect fuel mixture or ignition timing, can also contribute to elevated idle speeds. It's important to diagnose the specific cause to ensure proper engine performance.
The idle RPM for a 1994 GMC Sonoma typically ranges between 500 and 800 RPM when the engine is warm. If the idle speed is too low or too high, it could indicate issues with the idle air control valve, throttle position sensor, or other engine components. It's advisable to consult the owner's manual or a repair guide for specific recommendations based on your engine type.

The IAC valve is on the back of the throttle body. It has 2 bolts on the back of it and a black cylinder on one end. The idle adjuster screw is on the front of the intake and has a couple cables running to it. Let your car fully warm up and turn the screw to adjust the idle.
A high idle in a 2000 Cadillac Deville DTS when first starting can be caused by several factors, including a malfunctioning idle air control valve (IAC), a vacuum leak, or a dirty throttle body. The engine management system may also increase idle speed to warm up the engine quickly or compensate for a cold start. If the high idle persists after the engine warms up, it’s advisable to have the vehicle checked for diagnostic trouble codes and to inspect the related components for any issues.
