Why do it yourselves? Aren't you covered with a 5yr 60,000mi. powertrain warranty?Dealer should do it for $0.

I had the same problem at 43,000 mi. on my '04 V6. one coil failed on the highway which led to severe engine vibration and flashing engine light. I drove it back and they replaced all six and the battery(for some reason) all under warranty and they set me up with a car. When i picked it up the wipers wouldn't work and the radio needed to be coded. After looking at it the tech said it was calling for a "vehicle positioning sensor". That's why I have an '07 now...
