Airbus driver right now. Been on the -200, -300 & -400 for a number of years.
Don't screw around with the throttles. Wrong one and you die. Besides, you need the power so you don't lose altitiude (that said don't try to hold altitude in the recovery) Switch flight controls to stby rudder and problem will go away or at least be overpowered by the stby PCU.
