I am sorry that you have not been helped yet. I just came online and saw you question

Does it only occur when idling, when accelerating, or does it not matter.

Is it a light knocking noise or deep knocking noise?

Does it sound like it is internal in the engine or external to the engine

Please remember that I am not there to listen to the noise, therefore I rely on you for as much detail as possible
