Spark plug removal and installation

The old spark plug gasket perhaps?

No I think it came up from inside when I removed the old one

What could pop up into the the hole

This is the type of shit that makes me want to light a cigarette after quitting for the last 30 days

Pull it out and see what it is.

Start fresh code for crank sensor fixed it then 17 codes came up changed the ECM then 5 codes 4 injectors and cam sensor changed the cam first then I started on injectors and plugs pulled all plugs went to put in 2 and this donut was in the way

I was scared to but nothing to lose

What do you want? Remove it or take it to a mechanic if you cannot.
