1999 Cruise control problem

I didn't want to hijack the other cruise control thread, so here is my issue. When I set my cruise, it will sometimes just keep accelerating. Other times it will set on the correct speed for miles and then suddenly start accelerating on its own. Anyone else have this issue, or have any idea how to fix it?

I'll give you a bit of insight... I'm pretty sure you got a vacuum motor on your truck that controls the throttle. There is 3 valves that control the vacuum into the vacuum motor for throttle control. Maybe a valve is sticking???

Then there has been issues with the clock spring in the column before but typically it break and there is no control.

At least its something to chase...

Thanks for the reply. I don't know much about them, it just seems odd that I can be on cruise at 65 mph for miles and it will suddenly just begin accelerating, and keep accelerating until I tap the brakes.

Thanks again.
