Narrative:

Picked up aircraft X in ZZZ. The aircraft had arrived in ZZZ with a number 2 engine that was operating erratically and rolled back uncommanded. This occurred on the prior flight.

The engine start takeoff and climb were normal. After level off the number 2 engine began to become erratic. N1 was fluctuating as well as fuel flow. This would continue for several minutes then stop. This cycle continued and started to get worse so we [notified ATC] and recovered at the closest airport in point of time. [The diversion airport] had favorable weather. Upon landing the ECAM alerted us to a fadec number two fault and upon taxi in the fault message cleared itself.
