I'm also taking into account what I've seen in person. There are 5 other Ecoboost F150s in my area and none of them have experienced this issue. Only 1 has had one issue which was a harsh shift. He got it reflashed and hasn't had any other issues in over a year. These Ecoboosts around here see a pretty big swing in climate conditions throughout the 4 seasons in Maine. We have cold weather, snow, plenty of rain in the spring and summer, hot weather and a couple weeks of high humidity in the summer.

I've had it numerous times. I'm in southwest BC where the humidity is about 75% 8 months of the year (think 2 degrees Celsius and raining in the winter).

I got a new coil pack on one cylinder last week and it's made a difference.

I'm starting to think that the condensation causes the shudder in an otherwise healthy ecoboost but can trigger the heavy misfire if you have coil packs that are marginal. Just my 2 cents.

When the temp is 80 degrees humid and raining and you drive a few miles behind slow moving traffic then step on it hard it will seem as though it is going to quit running and bucks until you let off the throttle and let it clear. VERY DANGEROUS!!!!!!!!!!!
