well ford racing is sending a new sd card there is a reflash for 2012 thru2014 so we'll see more to come for code p219

You can try closing the plug gap. I had that code before and tightened the gap up and it stopped

I had it happen when I first installed my Procharger, cleared the code and it has never happened again. That was a year ago

The reflash did the trick

Well 400 miles later the cel light popped on when warming up p219a code called ford racing to see what they had to say.They were very helpful and are keeping me updated their engineers are looking over the new tune more to come. If they can't come up with something I will tighten up the gap on the plugs what gap do you recommend?
