So that is where the noise is coming from on my '02 2.7! Mine seems to only happen when car is slightly turning right. I thought that the tire rotating in this position somehow vented air across an 'undisclosed' opening and set off the sound, not unlike blowing over the top of an empty bottle but a little higher pitched. I will look into the cheap solutions and thanks to you all.

I'm kinda embarassed about this, but figured I should add to the thread for posterity...

When I read about the vent hole originally, I opened the filler flap and there it was, right under the cap. That's the hole I was taping - with inconclusive results.

But this weekend I noticed that there's another grommeted hole at the leading edge of the filler compartment - on the other side of the hinge point! It's kinda awkward to put an easily removed piece of tape over that hole because the leading edge of the flap goes past it, but doing that completely cured my howl.

Just another sad case of "Using The Wrong Hole"!
