Standard Ignition Idle Air Control Valve P/N:AC187

Hold a steady idle with the Standard Ignition Idle Air Control Valve AC187. It installs as a direct-fit replacement for the listed applications — the 1992-1995 Honda Civic and the 1993-1995 Honda Civic Del Sol — providing the factory air-bypass path the engine uses to manage idle speed.

An idle air control valve regulates the amount of air that bypasses the closed throttle plate, letting the engine control module raise or lower idle speed during cold starts, warm-up, and changing accessory loads. As it operates, the ECM meters this bypass air to keep the engine turning smoothly when your foot is off the throttle.

• Idle-speed control: meters air around the throttle plate so the ECM can hold the commanded idle.
• Direct-fit application: matches the listed Honda Civic and Civic Del Sol applications.
• Signs it may need replacing: rough or fluctuating idle, unexpected stalling, surging, or hard starting — diagnose the cause before replacing, as these symptoms can have other sources.

If a failed idle air control valve is the cause of your idle trouble, AC187 replaces it and helps restore normal idle airflow.
