Background: 91 Eliminator - cruise control would lock on and keep accelerating. I had to turn the engine off, coast to the side of the interstate and disconnect the cable at the throttle body. Picked up a "new" actuator (the vacuum motor with the cable to the throttle body) at P&P and finally got around to starting the replacement today. As I was removing the actuator I noticed a lot of slack in the vacuum line going diwn behind the bumper to the vacuum ball. I managed to move things around enough to see that there is no vacuum ball, just a screw in the rnd of the line. My question - Could the absence of the vacuum ball (reservoir) cause the cruise to lock on and keep accelerating? Or, is it's absence just coincidental (which is what I'm thinking)? I plan to replace the vacuum ball in either case, but need to know if it causes/contributes to the problem.
