Tada,
I am not sure how old is your car, but on my '07 the "accordion type" hose (link below) was cracked, loosing vacuum (and making a mess..), this hose connects the PCV located under the driver side intake plenum to the AOS
I also remember that when I remove it, it also pulled a connector that is in the same area (some type of sensor), just be sure that you plug the connector again if this hapens
