Does anyone know what that little hose is that connects to the plastic intake from under neath it by the TB? i went out to mine today and i noticed that it came off and i couldn't get it back on. so i then looked at my sisters and my sisters doesn't even have the hose (but it does have the stem on the intake.

 

anybody know what it is?

 

if the line is right below the throttle body, it would be a vaccum line....but if its on the front lower side of the intake then its the pcv valve
