How do you adjust the idle speed on a 1997 Toyota Tercel?

To adjust the idle speed on a 1997 Toyota Tercel, first ensure the engine is at normal operating temperature. Locate the idle adjustment screw on the throttle body, which is usually near the throttle linkage. Turning the screw clockwise will increase the idle speed, while counterclockwise will decrease it. After making adjustments, check the idle speed with a tachometer to ensure it falls within the manufacturer’s recommended range.
