Air Control Valve

Start engine. Turn A/C off. Rotate steering wheel right and left. Engine RPM should not decrease greater than 50 RPM. Pinch air hose shut. Rotate steering wheel right and left. Engine RPM should decrease about 200 RPM. If system fails any of these tests, check vacuum hoses and air control valve.
