I have a 96 with 318 . My cruise control sticks on sometimes..

As in , i tap the brakes and it wont shut off--the engine accelerates / throttle goes to the floor !! I basically have to stand on the brakes--and hold down the SET button.
Once i had to put it in neutral and shut the engine off !

If i press the on/off button, it wont shut off.

It does this randomly, i have changed out the control button deal thats on the steering wheel.

What would cause this ???
