Ok as soon as I start my car up, my engine starts to make this rattleing noise and when I press on the gas very slightly the rattle becomes faster, but then stops when my RPM comes close to 2k or so... My oil is fine, and the sound seems to be coming fromt the engine itself when i had the hood up checking it. Now I don't know much about cars, so I can't pine point the location for you guys but if someone has any ideas of what it could be please let me know. Thanks
