    Q:
    How is the EGR valve operated in different types of engines for the 1994 Chevrolet Astro? Posted by Customer
    A:
    In carbureted and throttle body injection engines, the EGR valve is typically diaphragm-operated and controlled by a vacuum source. In contrast, in central multiport and sequential fuel injection engines, it is electronically controlled without vacuum.
