1989 GT Cruise Control Problems

I have a 1989 Mustang GT that has developed cruise control problems.
When you set the cruise, it acts like it isn't doing anything, but if
you take your foot off the gas, and you gently tap on the
accelerator, then it will bring it up to the set speed.
Then, once you take your foot off the gas, it slowly creeps down and
won't go back up on it's own unless you lightly tap the gas again.
Has anyone else run into this problem? The accelerate button also
does nothing anymore, but the coast one does.
All lights, horn, etc work.
I would like to try to fix it my self if at all possible. I just don't
know where to start looking.
Any help is greatly appreciated.

Does it have ANY other problems? Especially idle speed problems?

That sounds like it could possibly be associated with a bad throttle
position sensor.
OR a binding throttle cable from the servo.

Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!

slowing down and not recovering can also be a vacum leak at the servo...

Thanks, I was told that there could be a hole in a vacuum hose, or the
servo itself could be bad.
