    humming noise

    alright so l let me first start the thread with i probably have a mild case of "new-car-paranoia", but i might as well ask anyway:

    Have a new '05 wrx sedan 5mt that currently has ~1100 miles on it. ive recently (it might have always done this but im just now noticing it) noticed that when the car is idle (and not moving) i hear this humming noise that is distintly different than the normal engine rumble. its comming from the engine bay (because its louder when i lift the hood up) and it sounds like vibration of some kind, but it has to be a really fine vibration because it sounds like a faint hum (like an electronic hum).

    anybody have any idea what im talking about or do i need mental help?

    i take it from the lack of response that i need mental help then.

    guess i wont be able to hear "it" when the turbo-back is installed anyway.

    It could be the alternator, mine produced a high-pitched whine for a while (I think!) that I no longer notice.

    Or it could be something resonating.

    If you hold off on modding the car while warranty is still in play you won't have to worry at all, anything wrong will be SOA's problem.
