03 Protege 5 Metallic Rattle In Engine Bay
My car makes a rattling noise in the engine bay during normal driving. The problem does not happen while idling. I've noticed that it happens most frequently in second gear at around 3000rpms. I can only hear it when the windows are rolled down or if I'm in a parking garage. I think it might be spark knock, heatshields, EGR, head gasket, or low octane fuel. I recorded some audio with my phone while driving.
