Went to diagnose this f250 a couple weeks ago for running rough. Injector data was a little bit off but seemed to be in a limp mode. Only codes were for the def header so ohmed it out and it tested bad. Replaced and was still running bad. When pulling the fuel filters I caught a hint of gasoline. Apparently was topped off with it by accident. He had tank drained and new fuel filters put on and said it’s getting better fuel mileage than ever now….
