The CC on my '89 LS Troop works (or doesn't) about as you describe. I got my rig about three years ago and it wasn't working at all at first. I found out with a little exploring there is a cable that hooks into the back of the gas pedal that does the dirty work inside the cab. I'm not sure what makes it work on the other side of the firewall, however. Yeah, it works, but much like yours. That is, not too well at all. I just stopped trying to use it after a while.

Merry Christmas
