Bronco Cruse Control

Dec 28, 2003 5 Replies

I am Bronco-sitting my daughters 88 vehicle for a while. I have been doing a few little thing on it for her, new shocks, tune-up routine maintenance etc.



Driving it I have noticed that when you use the cruise control it seems to surge instead of cruise. By this I mean that it seems to operate the way my wife drives. On the gas, off the gas, on the gas, off the gas, over, and over, and over forever. On level road, it's like a two/three seconds of hard acceleration then coast for a few seconds then back on the gas 'hard'. Is there any adjustment or anything that can be done to smooth this out.



I think this is why my daughter says that it doesn't get good gas mileage when she uses cruise control, going back and forth to college. Of course we know that a good driver can do better than cruise control on gas mileage, but the way this cruise control does is very irritating.


Cool! :)

LMAO! :)

Whew... :) ...the answers to the cruise control problem will be int'resting reading too. :)

usually when one surges, it is because the linkage to the servo is adjusted too tight

it must have about 1/8" of free-play, or else the CC will overshoot, then let off, overshoot, let off, etc

My '87 F150 had that problem when new. The problem was a Speed Control Module located in the passenger compartment under the dash. I suspect that your problem is related. I don't remember anymore details. Your '88 should be identical to my '87.

I've ran into that before, I've also replaced several servos that caused a surging problem. His best bet is to check the cable adjustment first though. Bob
