I know this may not make much sense unless you have experienced it yourself but ill try to eplain it best i can. when i am driving down the road and push the gas pedal theres a humming noise coming from my motor, from what i can tell it sounds like its intermitten with pushing the pedal, as i give it gas it makes the noise and as i oull off the gas it stops. If i had to gues i would say it seems like its maybe coming from where the airbox is. The noise is almost like a static frequency noise you would hear on a radio (if that makes any sense) other than when i am going down the road giving it gas i dont hear the noise at all, it does not happen while sitting at idle, and all my guages and everything else are absolutely fine. i have not noticd any other effects at all, other than its just annoying. i tried googling and some people were saying possibly replace the idle control valve... hopefully someone here has seen this and knows whats going on, like i said i havent noticed any performance issues but i would like to fix it befor anything goes wrong.
also this noise is most noticeable around 45-65 MPH
