      Idle Air Control Valve

      Taking an adventurous trip throughout the countryside can be gratifying, but not if you're noticing that your ride is burning more fuel than usual. Your idle air control valve (IAC valve) can efficiently control the amount of air flowing into your engine so your vehicle's computer can match it with the precise quantity of fuel. If you're noticing decreased MPG, rely on AutoZone's customized IAC valve to avoid potential problems and save more money at the pump.

      Your vehicle's performance relies on more than top-notch horsepower and shiny, chrome wheels. Many intricate components need to function well to deliver a smooth ride, including your idle air control (IAC) valve. Some common symptoms of a faulty IAC valve include the clogging of the valve with carbon, dirt and debris, which hinders the amount of air flowing through and slows the valve's response time. Another sign that your valve is defective occurs when your engine's RPM drops extremely low, resulting in an immediate, rough deceleration after you remove your foot from the gas pedal. This can lead to your tailpipe backfiring while the engine pumps an additional surplus of fuel. An aftermarket IAC valve from AutoZone can properly distribute the amount of air flowing into your engine, ensuring a well-operating and efficient ride.
