There was absolutely no object that hit the roof; the temperature outside was about 70 degrees, with the inside temperature a tad cooler at approximately 65 degrees; and the road around us was smooth and, as far as we could see, free from…

While driving on the williamsburg bridge there was a slight incline during this time the vehicle was trying to accelerate and that's when it started loosing power and started misfiring.

Traveling on interstate engine suddenly starts to stutter. Push down on the gas and there is no power. Car cannot go over 40 MPH. Engine light comes on. Take car to my local mechanic. Informed that ignition coils #1,2,4 are ruined. They are replaced, 12 hours later ignition coil #2 fails again. Mechanic gives me mazda bulletin #01-026/11 calling out issues with PCM and how PCM will cause mis-firing of ignition coils causing the coils to fail prematurely.
