when your driving in the msp going over say 35-40 miles an hour is the car supposed to make a rumbling noise, even if u shift into nertral? for some reason when im driving and im going 35-40 miles and hour its as if im hearing this rumbling noise in my car. i dont remember it doing this before. when im driving down the street acclerate to over 35-40 miles an hour and shift into neutral i can still hear this and it is quite loud. has any else had this problem or is it just me. thanks for any input
