2nd Gen Non-Engine/Transmission Cruise Control Hunt

[RClark]

When not towing at highway speeds on cruise control i notice a very small hunt, speed varying up and down about 1/4 mph. When I install SMARTY on timing only for mileage I get a 1 mph hunt.

I know the cruise control is controlled by the PCM. IS there anyway this can be reprogramed to eliminate the hunt?

When i used to install a CC on a car, J. C. Whitney sells them, it had a selector for 4, 6, or 8 cyl to control the sensitivity. If they could do that 20 years ago they should be able to do it now.

You have a vacuum servo under the ds battery. Install an 1/8" barbed needle valve onto the line and open it about 1/2 to 3/4 of a turn. If it responds to slow, open it 1/4 of a turn, repeat PRN.
