Cruise control

Sometimes my cruise/fast idle toggle does not work. I can jimmy it around or flip it off then back on and it gets it working again. I would almost bet your switch is worn out like mine. Or maybe your clutch pedal is not returning up to top all the way when you release it. Or the brake pedal. It is usually the simplest of things when a cruise switch doesn't work.

 

I am having a problem with my cruise control it high idle when parked but when am driving it doesn't I js bought the truck and did a a complete inframe it's a 12.7 Detroit oh and my Jake's stop working if anyone can help that would be really appreciate

 

Throttle pedal sticking and commanding 1% throttle?
