Saturn SL2 Intake manifold Problem

The intake manifold is making a knocking sound behind all the sensors. why is the intake manifold knocking? I thought it was my engine knocking but it is deffinitely inside the intake manifold.

changed the MAP sensor (which did not help anything at all)

There is nothing inside the intake manifold to knock so the knocking has to be coming from somewhere else.
