cruise control surging
The engine surges every few seconds with the cruise set, while on flat, smooth highway. Like its over controlling. Havent quite got a solid understanding of this system yet. Any ideas?

Check the thread titled "Power Brakes". There's a comment in there from Dave Long 667 that says replacing his vacuum pump fixed his cruise control. You may want to do a vacuum test to see if you're pulling 21". I'll be replacing my vacuum pump this week. My cruise was surging the first time I tried it on the maiden voyage back to Eugene from Portland. I turned it off and haven't tried it since but will as soon as I get the new pump in.

Does your vehicle speedometer work ok no flutuations.. your 94 has an electronic speed control..........no vacuum, but cable siezing is a known problem. If you need the manual I will send it later if you send me an email......

I'd like to pull the cable and lube it, does it remove from the control box easily? afraid the oil might effect the contoller
an e-mail is coming
thanks, Vince

Hi, I had a 1993 before and the dealer adjusted something in the differential, mine was doing that only with the camper in the box. I believe the pick up in on top of the differential. The speedo was fluctuating at around 60 miles per hours only woth cruise control on. this was a strange problem.
