ABSTRACT:
An improved idle speed control arrangement that embodies an idle air passage formed in a member of the induction system that is downstream of the throttle valves. The idle air passage is formed by a groove in a face of the member that is closed by engagement with another member of the induction system. The idle speed is controlled by controlling the flow of air to the idle passage from an atmospheric air inlet.
