The problem
THE IDLE CONTROL VALVE WHICH CONTROLS IDLE SPEED BY VARYING THE AMOUNT OF INTAKE AIR THAT BYPASSES THE THROTTLE PLATE IS SUBJECT TO BACKFIRE INTO THE INTAKE MANIFOLD. SUCH BACKFIRE CAN DAMAGE THE VALVE AND CAUSE THE IDLE VALVE PLATE TO REMAIN OPEN. CONSEQUENCE OF DEFECT: THIS WILL RESULT IN ABNORMALLY HIGH IDLE SPEED.
What owners should do
INSTALL A REDESIGNED IDLE CONTROL VALVE WHICH CAN NOT STICK OPEN.
