Check engine light came on a week ago and the codes were for multiple misfires. The first suspect was trash in gas because my wife had just gotten gas when it started. Today I'm driving to work and it begins missing and stuttering bad, it was a God awful noise. Open the hood and the ignition coil is broken and the part of it that goes down to spark plug(tube part) is literally hanging by two wires. It was like it was literally blown out. What could possibly cause this?

Sounds like you blew out a spark plug? Either it wasn't tight or it stripped the threads on the head for the spark plugs?

If you are talking about the actual spark plug wire that goes down the hole in the valve cover to the spark plug, it is most likely caused by a loose / stripped out spark plug itself. If the spark plug came loose, it will allow compression from the cylinder out and it will make the spark plug end pop off of the spark plug.

Sure enough. Yall are correct. Went to take the old spark plug out and couldn't find it. The new one did screw in so the old one must've just backed off over time. Thanks for the help guys.
