Engine knock sound on shutdown.

[Z3R0IN]

For the past few days I've started to notice a "Knock ,Knock" from under the hood as the engine turns off. No obvious loose parts that I can see. Wondering if maybe an engine mount is going or my blower is hitting the intake. Hoping nothing more serious. Just curious is anyone else is having this happen. Sear hasn't helped. most engine noise posts refer to the chirp.

Nothing like that from my truck.

So I have at least narrowed it down to it not being the motor. I think it might be the throttle body cycling and making noise. In the video you can hear it as it shuts off. And then so and it’s in Acc you can hear it cycle again. Then makes the clacking noise when I turn it off again.
