ABSTRACT:
A method of controlling an intake manifold tuning valve (MTV) for an internal combustion engine includes the steps of sensing the position of the throttle, determining whether the throttle position is greater than or equal to wide open throttle (WOT), and opening the intake MTV if the throttle position is not greater than or equal to WOT. The method also includes the steps of sensing the speed of the engine if the throttle position is greater than or equal to WOT, determining whether the engine speed is outside a first and second predetermined speeds, closing the intake MTV if the engine speed is outside the range between first and second predetermined speeds and opening the intake MTV if the engine speed is not outside the range between first and second predetermined speeds.
