Bendix cruise control

[Ralph L. Fullenwider]

Morning Bill:

There are 2 valves mounted on or near the control unit. I would suspect one
of those are sticking from time to time on you for the high idle. Since
your cruise is working the cc-5 is working and that is in drive but when in
N the air should be metered from those valves to the inversion valve and
conversely the cc-5. Back up a step or 2 from the cc-5 and see what you
come up with is where I would start.

Safe travels,
