my car seems to run fine at idle and low rpms. However, right when it breaks about 3200 i hear a loud rattling noise coming from the engine. It sounds like something knocking on metal really fast and loud. Other than this the car runs perfect. Any opinions? i can try to get a viedo sometime soon if it would help. Thanks.

Like marbles rolling around in a tin can. If so, it's detonation. What gas are you running and what's the timing set at?

that may not be a good thing, check your timing! And what gas do you use?
