Were to find the idle on 1989 Chevy Corsica?

The idle air control (IAC) valve on a 1989 Chevy Corsica is located on the throttle body. The throttle body is usually on the intake manifold, where the air intake from the air filter housing connects to the engine. The IAC valve is a small, usually cylindrical, component attached to the throttle body itself. It might be on the side or top, depending on the exact engine configuration.

To be sure, you'll want to:

1. Consult a repair manual: A Haynes or Chilton manual specific to your 1989 Chevy Corsica will have diagrams and precise locations of all engine components, including the IAC valve. This is the most reliable method.

2. Look online: Search for "1989 Chevy Corsica IAC valve location" on sites like YouTube (videos are helpful) or image search on Google. Be sure to specify your engine size (e.g., 2.5L, 2.8L) as this will affect the exact location.

3. Visual inspection: With the engine cool and the hood open, carefully examine the throttle body. The IAC valve is usually readily visible and easily identifiable due to its size and electrical connector.

Remember to be cautious when working near the engine. Always disconnect the negative battery terminal before starting any work to prevent accidental shorts.
