My 2019 - 115 HP SHO is running on 2 of the 4 cylinders. I've had my injectors professionally cleaned. On reinstallation I noticed that the rough running and no power condition continued. To check the individual cylinders I unplugged each injector and found no change when I unplugged #1 and #4. When I unplugged #2 or #3 the engine stalls.
I switched out the coils packs from #1 and #2 and the condition persists as above. Seems like #1 & #4 are not being told to fire?
