Hello - your description may cover multiple issues. The engine misfire could be caused by bad spark plugs, coils or even a fuel supply problem The knocking noise may well be a worn or damaged connecting rod or crankshaft bearing. The misfire would make a worn bearing situation worse. Check the engine oil level first to be sure the engine has an adequate oil supply. I would recommend an inspection of the engine knock (since that symptom may represent on-going damage to the engine) by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
