Narrative:
We pushed from the gate on time and taxied to the runway for departure. No abnormalities were detected during engine start or during pre-takeoff checks. After takeoff and during the climb we could hear a sound and feel the aircraft yawing right and left. Scanning the engine instruments we noticed the left (number 1) engine was surging. Fuel flow was increasing and decreasing; as were the N1 and N2 fans. Itt was also fluctuating. Fortunately no limitations were exceeded. I informed first officer; the flying pilot; that we needed to return. I then called departure and informed them of our need to return due to an engine issue. I declared an emergency and requested our takeoff runway. During our return; the number 1 engine began to operate normally. We landed on the runway and taxied to the gate. I amended the release with dispatch and informed maintenance of our situation and gate info. Maintenance informed me that this aircraft 'has a history' with the speed switches. While engine issues are sometime unavoidable; I would like to comment on the new checklist. Our total flight time from takeoff to landing was twelve minutes. The new checklist reduced our workload significantly allowing us to ensure a safe arrival.
