High pitched whistle

I noticed a high pitched whistle (like a high freq tone noise) with the car idling at

a red light or in park. It can be heard inside the car and outside. I even tried

turning off the radio and still does it. Any ideas?

I'd guess maybe the fuel pump? They can make a sound similar to what you describe...the noise is actually constant, but if it can be heard at all, it's usually only heard at idle because other noise drowns it out when moving or revving the engine.
