What can fail
The cruise control cable can slip out of its track on the cruise control lever and get stuck on the lever tab when you release the accelerator pedal. When this happens, the throttle stays open and won't return to idle.
What the fix does
Dealers will install a retaining clip on the cruise control lever tab to keep the cable in its proper track.
