Adding to the list.

Ignition coil pack #2 failure at 55k miles.
Spark plug wire failure (should be 2.2k ohms - read 8.5k ohms) at 55k miles.

Be forwarned, the dealer quoted me $18.90 for each of the 12 plugs. I was going to do them while I was changing the wires, but at that price, I'll hold off until 100k.
