    Minus 13 Sunday morning, had added power service (White for winter ) the night before , no block heater. Started right up dropped a cylinder for a fue seconds and cleared right up then warmed up like normal . Started driving and in 2 miles or less low fuel pressure came on turned around to go home and reduced engine power came on , by the time I got home the check engine light also came on . Later in the day the truck ran fine but now I have a check engine light on will this turn off on its own or do I need to go to a dealership to get it turned off ? Its a 2013 6.7 .

    Don't use power service fuel additives on the 6.7 PSD. I did the same thing last year and and I was always getting low pressure. Had to change the fuel filters and never had the problem again, and I also changed the fuel filters only 2k miles before I put the power service additive in, so the filters were not the problem. I only use the motorcraft fuel additive now. Cheap on amazon.

    For a easy fix for now just drain about a quart of fuel from the filter under the truck, cycle the key a few time to prime the fuel system and you should be good for now, but you will have to change the filters. The engine light is probably a low fuel pressure error or a contaminated fuel error. I know I had to clear some errors out after I had the same problem last winter.
