    Are you still having problems with your Explorer or was the issue solved with the replacement of the fuel pressure sensor?
    I'm still having problems with our 2017 Platinum.

    Sounds like one or both diverter valve(s) are sticking. DV's open on deceleration so as not to over boost the turbo(s) if they're sticking or sticky it would produce a surge under certain conditions...

    Continued Surge

    The fuel pressure sensor was replaced in 9 of 2020. It has had ABSOLUTELY no effect on the surge issue. I have been told, not thru "official" Ford channels, that the root cause of this syndrome is "Heat Soak" of the transmission torque converter. This seems to fit my group of symptoms: Occurs only after being run to temp, unit must sit off, parked, 10 to 30 minutes, then surges on LIGHT acceleration (gently pulling out of a parking space), after which, surge disappears until parked with engine off again.
    I intend to continue the battle until a resolve is reached. There are far too many of us with this problem for Ford to claim that they have no idea what what the issue is.
