Hi the cruise control works alright but has a little surging effect
.
what could be serviced for this?
More description required. Is it a little jiggly surge like a spastic
foot might cause, especially if irregular, or is it more of a long-scale
hunting effect? What is the time scale of the surge, in other words?
Jumpy speedo cable can cause it, as can poor vacuum supply. Or a bad
solder joint in the PID amplifier circuit of the servo system.
