Well the vacuum checks out OK. I guess it must be the control module? Anyone have an idea what it costs? Thanks! Brian

 

my 99 does just the opposit. when I engage the cruise the truck steadily increases speed. Its a real pia.... any ideas?......Dallas

 

No disrespect but how did you check your vacuum? Did you attach a gauge and driver around with it, or looked at the check valves for a few seconds?...lol.

Just askin. Some other guy says check under the battery tray for acid that may have literally eaten through the servo.

Good luck with your ride.
