All cars require a precise ratio of air and fuel entering the engine to enable efficient combustion. In modern engines, the idle air control valve regulates the air side of that ratio. When the valve malfunctions, the results are rough, stumbling idle and backfires, affecting your Pontiac's performance and fuel economy. Serious engine damage is also possible. The Firebird IAC valve is a direct-fit replacement engineered for years of reliable operation.
