Trying to resolve the DTC code above. The issue first started about week ago while cruising around 55 mph. The truck started running rough and felt under powered when going up slight inclines or at low RPMs in higher gears. I could not recreate the issue after getting home and started trouble shooting it later that evening. No error code was generated after that event. Today, a similar event happed while driving. After starting up the truck 7 hours later, it ran rough at start up and has continued to do so. This evening I plugged in my code reader and recorded the information before clearing the DTC's. I pulled the wiring harness off the #1 injector and it had some moisture in it so I used a compressor to blow out the moisture on both fittings and reconnected. That did not change the way the truck ran, though a code was not generated when I drove about 10 miles on the highway. The truck is a 2012 F 350, 6.7 with 181,000 mi.

Thanks for the help
