Fascinates me the laziness on some of these posts, " whistle or humming noise coming from motor i thought it was over heating but its not. " I mean can we please get some more detail as in is it happening while accelerating, while at idle, etc? I mean come on, you can't expect us to put you in the right direction just off your lazy description. SMH
