Questions about IAB and EGR

I am in the process of trying to find out why my car idles so high. I am slowly trying to eliminate potential problems.

Does the vacuum hose on the back of the EGR have a certain amount of vacuum at idle? I hooked my gauge up to it and it wouldn't register any thing. I put my finger over the end of the hose and I could just barely feel any vacuum .

I checked my IAB(I guess that is what that thing is called that mounts on the side of the TB). It was clean. I blew air into one side of it and could feel air coming out the other side. Is this normal?
