How to Adjust the Idle on a 1985 Chevrolet Camaro

Obtaining the correct idle speed is essential to proper engine function. A slow idle will make it hard to start the motor, create random stalling problems, and reduce performance from a standstill. A high idle, on the other hand, will waste fuel and place unnecessary stress on the drivetrain components. Adjusting the idle speed is as easy as turning a screw on top of the carburetor.

Tools Used: Flat-head screwdriver

Raise and support the hood. Twist off the nut holding the air cleaner in place and pull it off of the engine, exposing the carburetor. Locate the idle speed adjustment screw, positioned towards the top of the carburetor.

Start the Camaro's engine and let it warm up for at least five minutes. Using a flat-head screwdriver, turn the idle speed adjustment screw in either direction until the desired RPM is obtained. The idle speed should be set as close to 900 RPM as possible for stock engines.

Replace the air cleaner, screwing the nut back into place. Close the hood.

Tips & Warnings

If your Camaro lacks a built-in tachometer, you can use a hand-held tachometer instead. Follow the included instructions to hook it to the vehicle's electrical system.
