Hey volks,
  My foot ackes!  I have a sort of half functioning factory cruise set up in
my '88 vanagon.   When I engage the system it seems okay, but when we start
going up an incline, steep or shallow, it doesn't have enough pressure to give
itself the extra gas.  I find myself continually having to encourage it, which
I feel defeats the purpose of cruise control.   I have looked pretty deeply in
the archives and have come up with a couple of ideas along with those in THE
bently.   I  first thought it might be the throttle arm from the diaphram, so
I tightened it up as much as I could while keeping the idle constant.  Then I
checked the diaphram itself, disconnected the pump hose, pressed the diaphram
in, and it kept, no wholes.  I checked the hoses, they seem to be fine.  I
also checked the release valves on the clutch and brake levers, I have a
manual tranny.  Brake clicks, clutch faintly clicks.
  I don't really know how to check  the speed regulator which in attached to
the speedometer.  From what I gather it operates magnetically (?) somehow.  Is
there a way I can pin point this as a default.
Is there a way I can check the pump to see how much pressure it is producing.
I figure it has something to do with either the pump not producing enough
suction to increase the tension on the throttle lever or something to do with
the speed indicator.
I would like to keep the cruise in, although faily inefficient here in vt, but
its always a nice break.
any suggestion with be greatly appreciated.  sorry a little jumbled and long
