Angry Code P0352

Please help.....

I own a 2014 F-350 Super Duty 6.2 engine. Originally..Code P0357 came up. I replaced all 8 coils, 2 of them twice #7 & #2, 16 spark plugs and it still does not have any acceleration or horsepower when going up a hill/mountain, and then a new ECM unit was purchased, put on and programmed by the Ford dealership. Since having the truck back...now Code P0352 is showing. It doesn't want to go when leaving a red light, it is misfiring, jerking as I am driving and all around rough riding. My father in law is an Electrician and has checked every point of contact. The #2 cylinder is not firing at all. I am self employed and deliver trees, etc. for nurseries. I am losing money every day that my truck is not on the road and it is $$$$$$ing me to death.

Any advice on what the problem could be is welcome. I am at my wits end!!

Someone else will probably have better information, but if you've replaced both spark plug, COP and ECM the only thing left is the wiring. If it were me I'd inspect wiring very closely for cracks or damage, checking where the wire runs come close to heat sources or sharp edges.

Is the ECM commanding the #2 coil to fire AT THE ECM output?

P035x DTCs are set when there is an electrical circuit fault in the coil firing circuit for coil x. That means it could be the coil, the connector, the wiring, or the driver circuit in the PCM.
