Default Idle up VSV and the Air Switching Valve

Hello Everyone,

I have a 1989 Camry I am working on that has an idle up problem. I
have traced it to
a missing idle up air switching valve which is the diaphragm that is
hooked up to
the intake manifold and receives a vacuum signal from the idle up
VSV(electrical).

This ASV is hard to come by in our country and have it ordered. In the
meanwhile, to enable A/C idle up, I am just using the VSV for the air
bleed since it basically is an open/shut
valve that allows an air bleed to the manifold to increase the idle.

Out of curiosity, can anyone please tell me what the actual purpose of
the air switching valve diaphragm is since both parts are basically air
bleeds anyway? does it in anyway amplify
the bleed or just allows the idle up to be adjusted since it has a
screw on it. Can the car be run
without the diaphragm just in case I can't find it?

Thanks!
