Replace spark plugs on a ford freestar

Don't know if your misfire is the same as mine, at idle seemed fine but trying to do anything but a gentle accelleration and it was terrible. No check engine light either. Ford found one cylinder not firing due to a bad coil pack. They also changed the plugs which had 110k miles and a gap like the grand canyon (just kidding) and the wires. She's good as new (well almost). Don't know if your misfire is the same as mine, at idle seemed fine but trying to do anything but a gentle accelleration and it was terrible.
