Has nothing to do with the Throttle by wire. It is simply a motion of throttle on/throttle off done by the driver. The jerking of the car will make your foot on the throttle do this. Trying to fight this motion makes it worse since you react too late and only increase the on/off motion.

Do you mean the TBW acting up or something more? Then how does it happen with manual cars or cars without a TBW?
And the car can not engine brake from the 1st gear, can it? (and the problem occurs only in the 1st gear).
