Abstract
Systems and methods for operating an engine that includes two throttles that are arranged in parallel to deliver air into a single intake manifold are described. In one example, a first throttle is opened before a second throttle during a first condition and the second throttle is opened before the first throttle during a second condition. The throttles may be operated in this way to ensure even operation of the throttles.
