Zusammenfassung:	Methods and systems are provided for controlling air flow through at least two aspirators coupled across an intake throttle. In one example, a method includes, during a first condition, opening a common aspirator shut-off valve to direct intake air through a first aspirator and a second aspirator each coupled across an intake throttle, and supplying vacuum generated by the first aspirator and the second aspirator to respective vacuum consumption devices as demanded. The method also includes, responsive to a second condition, closing the common aspirator shut-off valve and supplying intake manifold vacuum to the respective vacuum consumption devices as demanded.
