    No, the rattle is a different issue going on, it sounds like a hiss when I press the gas pedal for about 5-7 seconds.......the P0446 code was given to me by a pep boys employee who used the scanner in my car, he said that it just said it was the evap circuit but wasn't specific on it so I really don't know
