running rough and black smoke
I have a cm870 that started running rough and pouring black smoke. Lots of fuel in oil. The harder you get on the fuel the worse it gets. I thought maybe a sticking injector so did a bubble test and no bubbles on front or back. Can a bad actuator make it run this rough? The egr is blocked. Turbo seems to be working fine.
