| In normal operation, the opening and closing of the throttle plate in the throttle body (via the throttle cables) determines the amount of air flow into the intake manifold. But in the EFI system, the ECM controls the IAC which opens & closes an air pathway around the throttle plate to supply air into the manifold during engine idling. | In normal operation, the opening and closing of the throttle plate in the throttle body (via the throttle cables) determines the amount of air flow into the intake manifold.
