[QUOTE="Vantango, post: 15661309, member: 187016"] and for the long version..The intake manifold runner control is an engine management component that is found on newer intake manifold designs. It is usually a motorized or vacuum actuated unit attached to the intake manifold, that controls the opening and closing of butterfly valves inside of the intake manifold runners. The unit will open and close the butterfly valves in order to provide maximum manifold pressure and flow at all engine speeds. While an intake manifold runner is not necessary for engine operation, it does provide the engine with increased performance and efficiency, particularly at low engine speeds. When the intake manifold runner control fails, it can leave the engine without the increased performance, and in some cases even reduce performance. Usually a faulty intake manifold runner control will produce a few symptoms that can alert the driver of a potential issue. Sent from my iPhone using svtperformance.com [/QUOTE]
