Funny thing....today I was driving and although I read this thread....I never noticed any noise at all...however today I had the radio shut off (ipod was left at home and I hate normal radio).
I heard a slight whistle as I accelerated...not a huge sound...but subtle...but it is there. Might this be a small crack in some air hose as other mentioned? Where would I look first...ideas? Pics?
I figure any pics or suggestions might also help the OP.
