Quick question on a hose I removed a while ago
 

Well there was a little vacuum hoes( I think) that was kinda broken so I just removed it not thinking about it because I couldn't find a place where it went. But Then I saw a buddies of mine. It was from the bottom on the intake below the sensor I believe. What does that do? Anyone know? I'll get pics if no one understands me.

is it in the back or the front of the intake, i mean near the distributor or the throttle body?

Or is it the one by the air filter box?
