03 Jeep Liberty engine knock

[Senterb]

I have an 03 Liberty that has an engine knock. When it is at idle it sounds fine. When you accelerate over 2000 rpms it starts knocking. Not sure if it could be a loose rocker or what. I included a link to a video of the engine running. Appreciate any help.

Update

I unplugged one cylinder at a time and it didnt eliminate the knock.

Got any diagnostic info? Does the engine shake if you rev it while in neutral?
