AOS Working Correctly?

Through a process of elimination I believe I have narrowed my problem to the AOS and related assembly. As stated previously, I've installed a new AOS. How often can they be faulty? A new AOS with a torn diaphragm seems a bit obscure. In addition, does the fixture that enters the intake manifold with the harness attachment play any part in the amount of vacuum? I've removed and inspected it, but it appears to be a pass through? Is there a vacuum reduction function withing the valve cover itself? I've had the valve cover off previously to replace the gasket. There were no parts left over?! I am quite out of ideas here. The car is a runner but not running correctly of course. I want to get her fixed to sell, so any ideas are appreciated.
