I have a 2017 Freightliner Cascadia DD13 that idles rough when I start it especially in colder weather. After my temp gauge comes up a bit, i shut it off and restart it and the light goes out and it runs good. It has a diesel leak onto an electrical connection I’ve wondered if could be causing it since the code is injector related. Any ideas?
