My 2014 PM 3500 just threw these codes at me. I got the P219A on 8/25/16. Unfortunately I was out of town and my driver couldn't do anything about it, so I had no choice but to let him run it. I just got home today, 8/29/16, and it threw the P0301. I'm guessing a fuel injector is the culprit. I just hit 250,000 miles and I've pretty much been problem free up til now. Anyone else had this issue yet? If so, just curious cost wise what I'm looking at.
