RE: rattling noise

You would probably get a better response to you question if you posted it in the model specific forum...

It sounds like detonation.This is a common problem with just about every car on the road these days.You could have carbon built up in the combustion chambers that is raising your compression ratio and causing the rattling sound.

This is a link to noise desriptions that could be of some help.
Spraying a fine mist of water into a warmed up engine can clean out carbon but you have to know what your'e doing or you can mess things up.

RE: rattling noise

It sounds like the same problem i am having. It almost sounds like there is something loose in the engine bay when the gas is pressed. The sound only happens though when i am driving. I first noticed the noise after i chipped my car.
