IF the knock goes away with higher throttle setting, get the oil pressure tested also make sure that the oil level is correct and not very low.

It sounds like a low oil pressure problem getting the pressure tested is a quick and simple check to see if pressure is below required levels at idle when this is known we can move on to other tests
