Default Cylinder 2 causing scraping sound?

I removed the spark plug connector and found out that it's cylinder 2 causing the problem. In video 1,you can see this.

In video 2, I floor it and you can hear that it can't hold a consistent throttle. It sounds like I'm pumping the gas but I'm holding it down steady.

Disconnecting and connecting spark plug cable. See difference in sound.


Now I floor it and hold it.
