CONDITION:

SOME OWNERS MAY EXPERIENCE A PREMATURE SEPARATION OF THE ACCELERATOR CABLE. ADDITIONALLY, SOME OWNERS MAY COMMENT ABOUT A DIFFICULT TO DEPRESS ACCELERATOR PEDAL.

CAUSE:

THE ACCELERATOR CABLE COMES OUT OF THE THROTTLE CAM GROOVE ON THE THROTTLE BODY. THIS HAPPENS WHEN SLACK IS ALLOWED TO ACCUMULATE IN THE CABLE AND A LOOP IS FORMED WHILE THE THROTTLE IS OPENED. WHEN THE THROTTLE IS RELAXED, THE LOOP OF CABLE MAY NOT RETURN TO THE GROOVE IN THE THROTTLE CAM BUT COMES TO REST ALONG THE SIDE OF THE CAM. A TYPICAL SCENARIO CAN BE EITHER LIFTING UP ON THE ACCELERATOR PEDAL WHILE THE CRUISE CONTROL IS ENGAGED AND THEN DISENGAGING THE CRUISE CONTROL OR IF THE FLOOR MAT IS ALLOWED TO BUNCH UP UNDER THE ACCELERATOR PEDAL. THE CABLE WILL RETURN TO THE CAM GROOVE IF THE THROTTLE IS DEPRESSED TO NEAR WIDE OPEN THROTTLE. THE CABLE MAY BECOME WORN OR BROKEN IF IT IS ALLOWED TO WEAR AGAINST THE THROTTLE CAM. IF THE CABLE BREAKS, THE THROTTLE WILL RETURN TO IDLE.

CORRECTION:

IF THE ACCELERATOR CABLE IS BROKEN OR SHOWS ANY SIGNS OF WEAR ON THE STRANDED WIRE END AT THE THROTTLE CAM, REPLACE THE CABLE AND INSTALL A CABLE RETENTION CLIP. IF THE CABLE IS NOT BROKEN AND THE CABLE SHOWS NO WEAR ON THE STRANDED WIRE END, INSTALL AN ACCELERATOR CABLE RETENTION CLIP. THE ACCELERATOR CABLE RETENTION CLIP CAN BE INSTALLED BY FOLLOWING THE PROCEDURE BELOW:

1. HOLD THE THROTTLE WIDE OPEN. THIS MAY EASILY BE DONE FROM INSIDE THE VEHICLE BY DEPRESSING THE ACCELERATOR PEDAL. 2. INSTALL THE THROTTLE CLIP OVER THE CAM GROOVE (FIGURE 1) IN LINE WITH THE EXISTING HOLE IN THE THROTTLE CAM THUS CAPTURING THE ACCELERATOR CABLE IN THE GROOVE. ROTATE THE CLIP UPWARD TO INSERT THE CLIP TANG INTO THE THROTTLE CAM HOLE. ROTATE THE CLIP DOWNWARD AND PUSH TO SEAT THE CLIP TANG IN THE THROTTLE CAM. 3. CLOSE THE THROTTLE SLOWLY. DO NOT ALLOW THE THROTTLE TO SNAP SHUT. 4. CHECK THE THROTTLE SYSTEM FOR PROPER OPERATION.
