Aug 19, 1997
THE CRUISE CONTROL AND THROTTLE CABLES ARE ATTACHED TO THE SAME THROTTLE VALVE ACTUATING LEVER AT THE THROTTLE HOUSING. IT IS POSSIBLE THAT THE PLASTIC BUSHING ON EITHER CABLE COULD BREAK DUE TO ENVIRONMENTAL INFLUENCES COUPLED WITH VIBRATION. IF THE BUSHING BREAKS, THE OUTER CABLE HOUSING CAN SEPARATE FROM THE BUSHING. IN THIS CASE, DURING APPLICATION OF THE THROTTLE PEDAL WITHOUT CRUISE CONTROL BEING ENGAGED, THE OUTER TUBE COULD CATCH ON THE EDGE OF THE BROKEN BUSHING.
Consequence & remedy
Consequence: THIS COULD CAUSE THE THROTTLE VALVE TO REMAIN PARTIALLY OPEN. IT HIS WERE TO OCCUR, THE CAR MIGHT NOT DECELERATE AS EXPECTED INCREASING THE RISK OF A VEHICLE CRASH.
Remedy: DEALERS WILL INSTALL A SPRING STEEL CLIP ON THE OUTER TUBE OF EACH CABLE IN THE AREA OF THE ADJUSTING SCREW AND PLASTIC BUSHING. THE CLIP IS DESIGNED TO PREVENT THE OUTER TUBE FROM DISLODGING FROM THE BUSHING.
