Injectors not opening.

I have been all over the car looking for vacuum leaks and I get know change in idle except for the very back side of the intake plenum flange it idles lower or rougher when I spray there. It is my understanding that spraying carb cleaner will make it rev when sprayed near a leak. I hear a whistling sound slightly and when I rev the engine it gets a little louder. I think it is coming from the IAC and when I pinch the PCV hose it goes away.
