v reg E46 lower inlet manifold rattle

Hi everyone I've got a v rev 318 E46 and over the last 2 weeks I've lost all power as if it's been thrown in limp mode , I've paid for a full diagnostic witch revealed no codes or issues what so ever ,on tick over it runs slightly rough if I blipp the accelarator it revs but I get one hell of a bang from the engine bay (not exactly sure where it's coming from) and it's not happening everytime I do it , when engine is hot the lower inlet manifold rattles as if theres somethin inside it but after taking the air intake off there's nothing that looks out of place or damaged , if anyone's had the same issue I'd appriciate the info on how you dealt with it , thanks

Welcome to the Werkz.

When you hear the bang noise does engine change its level of revs unusually (stumbles)?

Was there anything done to the car around the time the problem occurred? Different fuel, oil, serviced or different driver?
