When set the cruise control the speed surges up and down. I have replaced speed sensor in rear end & checked the ring in the rearened. The speedometer has been replaced and no change. I unplugged the controller behind the glovebox and the cruise works fine. However my ford dealer mechanic says it's no guarantee that is the problem. Also I have replaced vaccine lines under the hood. Please help, Thank You.
have the same problem?
