On a recent 3000 mile trip with my cat 3126b in a winnebago ultimate advantage I experienced low power and vibration along with lots of blow by on my tow car. I found another forum that helped me with some troubleshooting. I found that when I unplug the injection actuation pressure sensor the engine still runs. If I understand correctly this means it is bad? Would this align with the issues I was experiencing? Any help would be great. Thank you!
