no videos don't do us much good, if you can disconnect one plug at a time and knock disappears then it will probably be in lower end like rod or piston. you might try a compression test and get back to us but al should be with in 20% of each other clean throttle plate on both sides an d iac hole and check for vacuum leaks plus what I replied earlier is about all you can do.
