Honking from airbox at idle...

[Ewok_Fetus]

Hey guys, I am getting a honking noise, almost like wind over a bottle when my car is running at idle... I just changed out my PCV system but it isn't comming from around that area... It comes out of the airbox vents. I just changed my puck valve because when I took it off for the PCV clean/change, the diaphram came out in peices... Crumbled out. After changing that, it still did it... Any ideas? Also loosing a little boost... I though DV's only honked while under boost?

Tested the bypass valve... At least it still hold vacuum?! Dunno about boost though...

Hmmmm, I will double check that... It is kind of annoying... Did it ever go away? Also, I put my ear up to a screw driver then up to the suction pump to help locate the noise and it didn't seem to come from there... I think it was making the sound before I changed that too... I mean, the sound is comming right OUT of the airbox openings... Which leads me to beleive it is the DV/Pressure Reg Valve or maybe even the N75?
