★ Top Answer
The idle air control valve in a Mazda3 is situated at the front of the air intake, right above the throttle body. This valve is responsible for regulating the engine's idle speed when the throttle body butterfly is closed, ensuring a smooth idling experience. To replace it, start by removing the plastic engine cover and unplugging the electrical connector. Then, carefully remove the two bolts on each side, taking care not to drop them. Once both bolts are out, the valve can be freed, avoiding any damage to the gasket underneath. A new valve typically ranges from $30 to $40, and a reputable repair shop may charge around $50 to $70 for labor costs to install it.
