I would say, having replaced that danged valve 3 times on my 87 5kt, that
you should avoid second-guessing the computer and just pull the vacuum
hose at the other end (away from the valve itself), open the valve by
hand, and insert a golf tee into the hose end. Reconnect vac line after
flush.
Oh, and if you don't play golf, use a nail ;)
