I installed an equus cruise control system on my '85 1.9 (vacuum type)
and installed a vacuum reservoir at the same time.  The reservoir is the
type with its own non return valve and I've yet to have it "Kick out" on
me while climbing a hill.  I've had to downshift because the hill was
too steep, but the cruise control was still hanging in there at the time.

A good reservoir that holds its vacuum is the answer to that problem.  I
agree, though, that the full electronic types don't have the problem to
begin with.
