Cruise Control Surging Problem
The cruise control on my '90 E350 7.3L works, but instead of holding a constant speed it accelerates and coasts over a 10 mph range (approx.). It used to work fine, although it did the same thing occasionly during periods of high humidity. I've replaced the speed sensor, control module, and actuator (twice), with no change. There is plenty of vacume (19.5" hg). Any ideas? Thanks.

This guy has a troubleshooting guide for cruise control on his web site. He posts in the diesel forum for pre-powerstrokes.
