When my spark plugs were changed out the mechanic knocked the cruise cable out of the clip. He forgot to put it back in. I went to put it back in and the cable seems really loose, I don't know how loose it should be but now my cruise control doesn't work. The cable moves just a tiny bit when you set the cruise control. So how do I adjust this cable to make it tighter or to make it work? I looked at where it connected to (throttle) and into the engine but could not find an obvious way of adjusting it.
