1993 f250 7.3 idi delayed knock sound

[7IdIguy3]

I’m thinking maybe something to do with my fuel injectors? It sounds good at idle but when you give it fuel or bursts of fuel this knock happens . Listen closely and you can hear the loud ping in this video I tried to attach. Im stumped

It's very hard to tell from this video, but what I hear does sound like an injector knock.

I could not tell if the knock was the throttle linkage snapping back or an injector.

But I did not hear a loud ping. If that knock noise when you let off the throttle is what you are talking about, is not the throttle linkage smacking back, then ditto on what IDIBronco said about the injector knock.

I thought that I heard the knock when as he revved the engine, not when he let off. That couldn't have been the linkage snapping back.
