Noises problem
1994 Ford Explorer Four Wheel Drive Automatic

I heard a pop in the engine and it started to sound as if though something was flapping and the engine rattled very bad. When i went to look at the engine i saw that it was a spark plug that had been blown. The explore still runs, but not as well. I was just wondering if its just the spark plug that blew up or if the piston is damaged as well?
