    New here and thx for add. Own a 2017 base model 3500hd dually. When demanding throttle it shudders/studders acts erratic. Only kicked code once which was p0191. I cleaned map sensor which was super dirty. 120,000 miles. Just changed fuel filter and motor oil to eliminate that. Not sure if dirty...
