Check all fluid levels first, but it sounds like a detonation problem. I would try running seafoam through with the gas. That will loosen up carbon buildup in the cylinder head/piston area. NAPA and autozone sell it....

do a compression test to see if all your cynliders are healthy or not. knocking noise usually means a bad rod which could end up being a blown motor if not taken care of

any power loss? anything else that is going wrong with the car? a rod would knock like that as well.
