Annoying sound I have a loud wooooo noise that changes pitch with the engine rpm.It only shows it's ugly head after driving awhile.
When it does it,I can snap the throttle and it stops for a second,but then it starts again.
It sounds like it is coming from the Throttle body to me.Could my gaskets be bad and when they get hot they are expanding letting air in causing the awful noise? I was thinking about taking it off and giving it a cleaning anyways,so replacing the gaskets would not be a hassle.
The car runs fine and no SES codes.
Ideas?

Took off the TB and cleaned it and replaced the gasket. I drove around a little and no noise. Not going to get excited until I drive around tomorrow to see what happens.

Well,
the sound is back,BUT I know what it is.
There is a rubber line underneath the throttle body that attaches to a metal line that goes to the PCV valve. That rubber piece is so worn out that when it was getting hot it was getting sucked closed.I actually was making the noise come and go by moving that rubber piece around. Down to the parts store to get some hose.

Yeah, I would be VERY surprised that an SES light/codes would not be thrown (along with the rough/bad/reactive ECM enrichment/idle hunting) by a TB gasket leaking that badly!!
My car did all of the above just from the stupid little o ring type gasket that seals the EGR pipe flange into the top of the intake being a little tiny bit out of shape.
