Jim,
the only thing (that I knopw of) that can cause idle
that high with the throttle body closed is an idle
control valve opened all the way. Remove the plug from
the valve (with the engine off) amd see whether you
have normal idle. If yes, the idle control unit may be
shot. If no the valve may be stuck open. You can clamp
the hose to the idle control valve to see whether that
brings down the idle. If so get a new idle control
valve. It's fine to disable the idle control system
for a while. The van should run ok without it.
Hope this helps,
Reinhard
