#6,#8 coil issue.the letter is the same as starting from the number a/1,b/2,c/3 and so on.you will get the same code if you run the engine with a coil unplugged instead of a misfire code.

passengerside 1234,driverside5678.i have seen alternators cause excess rf noise and cause engine misses.disconnect the ham radio and recheck it.
