In some cases an issue like this here can be caused by a fault with the throttle body itself needing replaced.I have seen several throttle body failures in the past before cause this fault needing replaced.I would have the codes diagnosed to see if this is the cause here for sure and to see if any other components need repaired or replaced for this fault.
