    Q:
    How does the AMS operate for the 1984 Buick Century? Posted by Customer
    A:
    An engine-driven air pump injects air into the exhaust ports, exhaust manifolds, or catalytic converter. It operates continuously while momentarily bypassing air during deceleration and high speeds through the Air Management Valve, with a check valve preventing backflow of exhaust gases.
