I have a 1999 Regal with 132000 miles. Recently, I've been getting this humming/whistling sound when I accelerate at lower speeds and usually only makes the sound around 2300 rpms then will stop somewhere past 3000. I really cant hear anything on the highway when I step on the gas. If I accelerate slow so the rpms dont reach near ~2300 then it wont happen. Does anyone have any idea what could be going on here?

Your help is very much appreciated.

Thanks
