Narrative:

About thirty seconds after takeoff; I saw a flicker of yellow coming from the engine instrument display. The number 2 engine's egt was fluctuating substantially; but not going into the red overheat condition. The captain and I elected to initially see if it would settle itself out. It did not and so we elected to return. The engine was left running and a discussion about possibly needing to shut it down took place. [Requested priority handing with] ATC by the captain and an uneventful overweight landing took place. The aircraft was cleared off the runway on our own power and the number 2 engine was shutdown. Emergency trucks saw no issues and we taxied back to the gates single engine. Following our arrival; a rep met us and conducted a quick interview to make sure we were able to continue with our duty day. This was very good and both the captain and I felt fine to get a new aircraft and continue with our trip.
