A Buick Century idle air control valve controls the amount of air going into the engine, allowing the vehicle's computer to match it with the right amount of fuel. If you notice that the Century IAC valve is clogged with debris, dirt and carbon, you must replace it with a new one to prevent slow valve response time. Visit AutoZone to ask our helpful staff about your options. Also take advantage of free battery charging and engine diagnostic testing so that additional areas of improvement are identified quickly, and enjoy access to our Loan-a-Tool program for easy installation.
