10mph Change

My cruise control will vary about 10mph. Ex. Set cruise at 60. The speed varies between 55 and 65 mph on flat,straight roadway. Does it sound like an adjustment or part replacement time? I know nothing (yet) about cruise.

It probably the age of your truck. So I wouldn't worry about it to much. The older cruise controls (in my experience) in these truck never were very accurate and trying to fix it is probably more trouble than what its worth. I'm just happy if it works in these trucks(80-86 that is).

Which truck is the problem on? If the vacuum hoses have a leak, this may cause your problem.
