Cruise Control gurus............question
Cruise Control gurus............question Whats the most common thing to make these systems non-fuctional?
Mine will set and hold a speed......but then it will very slowly start to slow down. Also, when I am on cruise control.....then I hit the accelerate button, it will accelerate till I let it go, but then it will fall right back down to where it was, then again slowly start to slow down. It cannot hold speed.
Any thoughts?

Unless I'm totally missing something (which isn't uncommon), the cruise control is run all electronically and not by vacuum. It's the signal from the VSS that the cruise control module uses to adjust the throttle.
I wonder if it's possible that your stepper motor (that controls the cruise cable connected to the throttle body) is going bad? I don't know how to check that though...
I just read some more stuff and it says that the cruise control is supposed to be able to accelerate and decelerate by increments of 1mph. On my cruise control i have the option to accelerate, but I have yet to figure out how to decelerate by 1 mph increments. I've only been able to turn it off and then "set cruise" at a lower velocity...
For your situation it sounds like the "decel" signal is being continually sent to the cruise control module.

LOL! I just now found that out on the way driving home. I thought "Hmm...there are only so many buttons to press. Lets hit this one again." It will incrementally decrease if you just push the set button instead of holding it (after setting cruise of course).
To the OP, perhaps your "set" button is sticking or something, so it keeps sending a signal to the CCM telling it to slow down.

But I thought regardless of a 3/4 channel car, the cruise control hooked up to the vacuum container in the fender?
