Default 2002 Durango 4.7 What is sucking air?

Standing on the drivers side there is an air noise. I found the noise, there is a small hose that is sucking air. When I pinch the hose the truck immediately starts to idle better. What is it and what is it supposed to be attached to?

Moved to the correct section.

Its a vacuum hose and no idea where it goes, but it connects to something. Look for open ports around the throttle body and/or valve covers (PCV). A pic would help us help you.
