    Random throttle closing

    2018 Roush F150 (supercharged). I'm having an issue where the truck with randomly close the throttle body at the top of second gear. I can run the truck back to back 10 times and not do it and every blue moon it will. I finally caught it on a data log (attached). Any help would be grateful.

    Anybody have any ideas? I've tried everything I can think of with nothing fixing or changing it.

    I can't open the file. Check your driver demand tables and driver demand torque ratios.
