The correct air-to-fuel ratio is critical for proper engine and idle functions, and the idle air control valve for Subaru Outback is one of the main components. It allows air into the engine, which is then mixed with fuel and sent through the combustion cycle. Dirt and debris keep air from getting into the valve, so the motor gets too much fuel and backfires. Replace a defective Outback IAC valve with a new one from AutoZone to restore your car's reliable nature. We guide you through the repair process with trustworthy advice provided by helpful staff, and you can benefit from free battery charging and engine diagnostic testing at the same time.
