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 ???

sounds like the cruise control servo/control unit as gone bad

where is that located sir--and whats it look like

It is most likely the clockspring control located under the steering wheel.

If yours is the same as the 92-93 I have two good used ones.

I replaced the clockspring a couple years ago with a good one.

My 92 would sometimes stick. The cable going from the throttle body to the vacuum actuator would stick. Spraying wd40 on the cable would fix it for a while.
