A co-worker of Sean's had been having some problems with his Taurus. The check engine light was on due to a misfire, and it was running quite roughly, so he brought it over for plugs and plug wires. I also changed the fuel filter. It runs much more smoothly, and after disconnecting/reconnecting the battery, the engine light shut off. I wanted to clear the codes with Sean's OBDII tester, but it wont communicate with Fords for some reason.

Anyway, here's 2 pics of the engine. The front 3 spark plugs were easy to get to. The rear 3 you can't see, and were a bit of a pain.
