the vents run off a vacuum line at the back off of your intake under the hood see if you can find it it might be pinched or disconnected

the line will be comming from the passenger side and connect to the map sensor and on the passnerger side of things. Just reach back there for something and you should be able to do this without taking the manifold off, (that is only if its just disconnected)

Almost certainly a vacuum line problem. Could be loose or deteriorated.
