    2015 f150 2.7eco stumbles after refueling

    here is alog of a 2015 2.7 eco all stock. fuel trims -28 and then misfires. seems to correct itself after it pegs af lean 20af. once it corrects it will idle and then start trimming negative until its -28 and then it will misfire again. it does this about a dozen times only after refueling and then it wont do it again. log attached. anyone have insight on this?

    are you topping it off when you refuel? Dont click the handle more than once after it clicks off the first time.
