Volks,
I have the idle stuck at 4500 RPM problem on an '86 Westy.  I have been
running the van for quite a while with the valve unplugged.  I have traced the
problem to a fried component of the idle stab control unit.  I am about to
pull it again to replace the burned component.  I would think that with the
idle stab valve unplugged it won't be a problem to drive the van with the
control unit on the workbench.  Is there some other function the control unit
performs?
Is it OK to drive the van with the control unit pulled out?
Thanks
Dan
