Its really weird to be honest, it almost sounds like a loose rod in the motor or something but at idle it sounds like a loose rod like a bottom end knock almost, but outside of car u cant hear it, but inside car u can. ( No radio in my car its pretty much stripped out ) . But if u put ur foot on brake and it brings up rpms a bit to prssurize system it disapears and u also dont hear it at all when ur driving...? Any ideas? Possible it is a loose rod but when the cars in motion the force keeps the rod from rattling? i dont know
