The problem
THE FAST IDLE CAM ON QUADRA-JET CARBURETORS CAN CRACK AND ULTIMATELY BREAK APART. IF THIS OCCURS AND PARTS FALL INTO THE THROTTLE LINKAGE, IT COULD CAUSE THE THROTTLE TO STICK IN A PARTIALLY OPEN POSITION.
Risk
UNEXPECTED LOSS OF THROTTLE CONTROL MAY RESULT IN ANACCIDENT.
What owners should do
INSTALL A NEW IMPROVED FAST IDLE CAM.
