I have a 2019 f150 and having several issues im think are all related to one problem. Truck sometimes will fight itself idling and fuel trims will be constant up and down. Also at WOT truck will get past 5500rpm and start adding fuel. The Rpm will increase smooth but on data log I notice around 6900rpm it will dip and decrease a little say to 6880 and then begin to climb again smoothly. Also have noticed control module voltage will randomly drop down to 12-13v when it normally is around 14.5v The truck has new injectors, battery, alternator. Just kind of lost at this point on what?s causing these things to happen.
