Thanks RG. I actually had it plugged I just needed to know what it was.

I took everyones advice and bought a MityVac, And your right it's an awesome tool!
Here's what I found:

1-Brake booster held 71/2" and never fell. Yeah!!
2-Check valve was bad, needs replacement.
3-The line going to the Vacuum switches under the black cover on top of the valve cover didn't hold vacuum at all. In fact you can hear the leak as you pump the vac. So I'm going to need 2 new vacuum switches.
4-the vac switch line also doubles back, t's off with 1 line, Black, running back into passenger compartment. That line also does not hold vacuum. I'm not exactly sure what this line does.
5-The EGR valve does not hold vacuum and I could not see it move. Does this mean it's bad?

That's all I found everything else checks out good.

I feel a lot better now knowing what I'm looking at. I really hate vacuum leaks!

Thanks everyone for all your help.
