I just took a 1500 mile trip out to Iowa to buy a new trailer. Stopped for fuel 50 miles prior to my arrival then started the truck and had a bad stumble and hesitation for a few seconds then cleared up. Check engine light was on with these two codes. I went to a Ram dealer right down the road who checked it out and performed a software update and said it was all set. 1200 miles into the trip back CEL came back on while driving with the same two codes. Truck was running fine this time so when I stopped I cleared them out and hasn’t come in again since. Anyone else experience these two codes together?
