I would still recommend getting a reader of your choosing
I get a check engine light when I am really pushing the rig on a hill when towing, or pushing the rig on a downhill with the tranny doing the work
It is always a random misfire
I clear the code when I get to my next stop
If the code continues or I feel the rig running rough or weird, I will then take it in to ford to look at
