I have had a sound when I step on the accelerator that reminds me of gravel or "static" like you see one a tv station with no channel aka white noise. That is the best way I have to describe it. It only happens when I have the pedal depressed, not at idle or coasting. This was present for a month or so and then resolved for a month but was back the last 2 days.

It is often only after I have driven for awhile and then the next day there is no problem. You can hear it best with windows up. I just read about 13 pages of searched topcis for this and there were a couple that sounded very similar but nobody ever had resolution so wondering if anyone had some new ideas.
