Help, my 2016 E350 wagon with less than 60,000 threw a check engine light when I started up the car one afternoon. It had been sitting for about 2 hours in the office parking lot and when I went out to lunch the car immediately had a very rough idle. I immediately put the car back in the parking spot and left it overnight to get my scanner from home. The next day, the check engine light codes are Module $07EB, $07E9, and $07E8 with the following codes P0356$07E8 and P0306$07E8 under Module $07E8. No other codes were found under the other modules.
The spark plugs were replaced at 45,000 miles.
I'm planning on replacing the spark plug coils. Double-check the spark plugs and ensure the gap is within specifications. Should I be looking for or doing anything else? Your advice is greatly appreciated.

Thanks,

1- Swap the questionable coil with another cylinder

2- Reset active codes with scan tool

3- Does fault stay on cyl.6 or follows coil ?

The rubber boot is the fragile piece between coil to plug available as spare.

Get all 6 plus dielectric lube.
