Default Strange Knocking Noise? - 08-20-2020, 10:57 AM

I bought the car with fbo, it drives fine and I don't hear anything. But when I'm idling and rev the engine to about 3k and let it drop back to idle, I can hear knocking noises coming from the bottom of the car and it faintly shakes a bit then it all goes away.

Here's a link to the sound I recorded
