I just purchased a 05 mazda 6 and i noticed that when the car is in drive at a stoplight i hear a rattle . If i put the car in Neutral it goes away .Is this normal. Otherwise the car is super quiet but the rattle gets annoying.Thanks in advance

 

Its probibly something loose in your engine. Check to see if everythings tight.

 

could be the heat shield of the muffler rattling (loose) happened to me on other cars
