I had a quest in the shop that had a rattle from the front. It wasent just on bumpy roads either, if you did some hard snap throttle shots you also heard the same rattle. turned out the front cat had come apart inside. that vehicle also ended up getting a long block since the cat peices got into the cyl's. It had better then 30% leak down in 2 of the front cyls. Not sayin this is whats wrong with your car since so many things can cause a rattle but it is something for you to consider.
