The volume of the rattling sound can also vary, I can make it louder or quieter depending on how heavy I press the throttle, also the rattling sound sounds like it is coming from the front half of the vehicle, mostly the engine bay area I suspect, but being limited on where I can sit to hear the noise I cannot pin point exactly where the noise is. It also sounds something close to metal hitting metal, and can be heard more vividly with the windows down, but does not limit the rattling sound to being heard while the windows are up, it simply sounds like a slightly muffled version.

Is it a sort of metallic rattle that happens under acceleration? Goes away once drivetrain settles out?
