Thanks for the donation. Much appreciated

The car is probably knocking at all speeds but gets quieter the faster the engine is turning. I would have a tech look at the vehicle to determine where the knock is coming from. I doubt it is just a bad spark plug?

If need a spark plugs engine would be running rough and have a misfiring codes
to have a knocking sound at idle check oil and oil pressure
check and make sure have the correct oil filter
Check belt and accessories driven by it
