We had a sudden "popping" (on start-up) and rattling (ongoing) sound this afternoon with our 2003 Marauder.
We limped it home, and it did throw a code: P0357, which points to the COP on the #7 cylinder. We pulled that coil-over-plug unit, and the plug came with it.
The plug had been bouncing around in there and it's upper electrode was smashed all the way down.
The REAL problem, though, is: it took the cylinder head threads with it. No threads left in the #7 spark plug hole.
So, I'm looking for recommendations. Specifically, has anyone had success with this:
