Screw the plug back in with the insert still attached to the plug. Someone stripped out the holes on the plug and then used an insert on the head as a repair. I would drive the car to RPMM and have them install another insert.

Here is a "how to" video, but I would not try this at home!!!

I highly encourage you to do like Todd said. As simple as it sounds ....this can turn into a head job with just a few wrong turns. He can also diagnose the Misfire to insure that the problem dont lie with the insert!

I had a similar problem it started with a annoying ticking sound, I could not figure out what it was no check engine light but did notice the car driving like crap. Finally check engine light came and it was a misfire on cylinder 2 so I checked it turns out the plug was way loose and it looked really bad. I replaced it with a new plug and fixed the problem. I'm still wondering what caused it to come that loose? And if it could happen again.
