cruise control acting weird
 

So this weekend was the first time I had the car on the road for a decent highway roundtrip. I decided to try out the cruise control to see how it worked. It worked, but the problem was it kept accelerating/decelerating +- 2-3 mph after it was set. Any thoughts/insight on how to fix this issue?

I would start by making sure the throttle linkages are lubricated and not binding. If that's not the problem, the other major components are the amp and the actuator. These guys have some trouble shooting info:

Thanks! I'll look into that later and keep you posted.
