Run High Octane in it and see if it helps you might have "spark knock". If it reduces the noise or makes it go away its spark knock

no no no....take it to a good mechanic an let them listen to it...dont try an fix something that isnt the problem if you rev it up in neutral an the raddle knocking sounds come in then most likely you have a rod knock....if you take your oil pan off an take the griddle out an oil pick up you can move the rod back an forth then that isnt good....you can fix it now an be ok unless you went to the brass on the bearing then it tore the crank up then you eithe rebuild it with getting your crank Micro polished an new bearings or get a new engine JDM 40-60k miles

If you rev the car and it gets louder then its a rod.More than likely drop the oil pan check pick up for shavings.
