Cruise wont hold speed...

[faceboy]

Just got my 3gee on the road and noticed that my Cruise Control works fine but drops about 5mph every minute or so, its very gradual and I didnt really notice until I had a nice pile of cars waiting to pass me on the highway...
Im thinking, well i know, its a vacuum leak, but I've never messed around with a cruise unit before. So I'm asking what hoses should I replace or how should I go about repairing the problem?

It's probably one of the valves not holding vacuum... more then a vacuum leak from a hose, but if it is a hose, most if not all of the hoses associated with cruise control are on the drivers side of the engine... hopefully it isn't something inside the actuator leaking, there are O-rings and such on the inside.

To know the exact hose number I need to know if you are fuel injected or carbureted... since they are most likely different.
