To slow the cold start idle on your 1991 Mercury Capri, you can adjust the idle speed using the idle speed screw on the throttle body. Additionally, check the coolant temperature sensor and the idle air control (IAC) valve to ensure they are functioning properly, as they can affect the idle speed. If needed, you can also tweak the air-fuel mixture for optimal performance during cold starts. Always consult the vehicle's service manual for specific adjustments and procedures.
To adjust the idle on a 1984 Mercury Capri, first ensure the engine is at operating temperature. Locate the idle adjustment screw on the throttle body; this is typically a flathead screw. Turn the screw clockwise to increase the idle speed or counterclockwise to decrease it, aiming for the recommended RPM specified in the owner's manual. Finally, check the idle speed using a tachometer and make any necessary fine adjustments.
