So I got my IS and after driving it for a few days I notice that whenever I pretty much start the car in 2nd, there's this rattling noise that I hear coming from maybe the engine area or under the car? Kind of hard to describe, but maybe something is shaking and it's not suppose to? Only happens once in a while too and not all the time...I think it might have to do something with me starting from a dead stop or just slowing down for a second at a stop sign. The noise only lasts for a second or two and after I pick up some speed it goes away. Sure didn't do this with my old prelude though..so I think something is up, just I don't know what. Any suggestions...?
