I have 2 2018 HD10 models. As a general rule they DO NOT TOLERATE DUST! I use mine on a ranch in Nevada and anytime I am around dust, which is every time I drive one of my machines, I have rough idling and eventually a dead engine. The solution for me has been if you hit 4000 RPM and the check engine light comes on. It’s a fuel problem. Change the fuel pump or the filter or both.
If it’s not that, change your electrical components in the ignition, including plugs, wires and coil. If that doesn’t do it, change your injectors. So long as I do that every year each of those components machines do pretty good. They were really not designed with the fuel injection system for dirt in the air..death penalty defender.
