For those that also have this whistling please do me a favor and disconnect your idle air valve tube from the plenum and then rev your car.
Does the whistling go away?
Mine does.... which leads me to believe the whistling is coming from somewhere in the idle air valve circuit.
I started a thread on this recently....no real solution but there was one comment that might lead to a solution.
gunk accumulates around the idle air valve so that it doesn't close 100% therefore causing a whistling sound.
I wanted to pull the idle air control unit out to clean it when i swapped a throttle actuator but i could not for the life of me disconnect the damn air tube without having to remove a bunch of other crap so i gave up.
If someone removes their idle air unit and cleans it and the whistling goes away let me know!

this valve closes under acceleration?
