	Now there seems to be a third type, with a partially-open default
state.

	I assume cars with these have no throttle body adjustment screw?


Yes, that is almost correct.  The screw on the 1988 90qs is backed out to
full throttle closure, and later models dispense with it altogether.  Note
that this type ISV looks like your VDO description, and I vaguely recall
that it is a VDO.
