Phil responded:
	Depends how he cleaned it out.  According to the book, inserting
	ANYTHING into the working bits is verboten.

	I have new Quick ISV Test - disconnect it and try to blow/suck
through
	it.  A good one closes completely, and you'll have trouble.  A bad
one
	sticks partly open and should describe a long arc over the back
fence.

	Any comments on this test?

The ISV on the 1988 90qs goes past closed when unpowered, presumably to
provide a limp home mode if unpowered.  It will pass air easily unpowered.
