I have a 2019 Vision ISB 6.7 77,00 miles engine#7425787
setting code 5898 engine misfire cylinder 4
it runs good no strange noises
I have cleaned the exhaust gas pressure tube and it has a new oem sensor
adjusted the valves
updated the ecm hc80283.11
it passed the air handling and injector performance test.
I swapped 4 and 3 injectors.
I checked the fuel pressure.
and cleaned egr differential ports
no improvement
any advice would be appreciated

did the code follow the injector or stay in hole#4 if it followed then its an injector if it stayed then its electrical, if its inactive put the fuel conditioner to it and drive it , if it stays on the back roads drive it in drive and not overdrive so the rpms stay up
