In a normally aspirated car it has vacuum in the manifold and slight pressure in the exhaust. It is normally only open a little at idle, opens more at light throttle, and closes during heavy throttle. I don't if it would really affect your idle speed much or not.
The few, the proud, the boosted!
13.788 @ 103.73 mph (3/2011) 320 whp and 300 ft/lbs torque. (3/2011)
