Can I test the air reg on a 77 by appling voltage to it? Should it open or close? It'll make my care rev high when I first start it and then the idle slows down after a warm up period. But it seems erratic and I don't think the diaphram is opening and closing like it should

Thanks!

A good way to test the operation of the unit is to put it in the freezer for 20 minutes, pull it out and look throught the in/out ports and be able to see through them. After it warms back up it should close and you should not be able to see though it.

If you have an erratic idle you should check ALL of your vacuum lines and fittings, and vacuum leaks cause erratic idle.
