unknown noise
i own a 2005 f150 supercrew fx4. today as i was attempting to go out of town i was accelerating up hill and heard a noise, sounded like air coming through a window seal or scratching, which is not the problem. the noise only came on when i increased the acceleration, there is no power loss, the truck still accelerated properly and had good power, just that the noise came on. so i returned home only to hear the problem on flat land also, when pressing the gas to accelerate. the truck seems to idle fine and have no problem with low acceleration.

I would check the air filter and intake tubes for proper fitment.you may be hearing air getting pulled into the motor through a leak in the intake setup. That wouldn't cause any codes, damage, or running issues but it would sound similar to what you have described
