On climb out encountered left engine limit surge stall high EGT and vibration. We leveled off and power came back and left engine was then operating within limits. However there was some vibration. We declared an emergency. We then completed the Engine Limit Stall Surge Checklist and chose to keep engine running. We advised ATC that we wanted to return. We briefed flight attendants to expect a normal landing and we would be landing within five to ten minutes. ATC gave us vectors for the ILS. We had a normal smooth landing at 206;000 LBS. We cleared the runway and shut down the left engine. Emergency vehicles followed us to the gate.
Climbing out at about 4;000 FT the Number 1 Engine EGT spiked into the red and the engine started to surge. This only lasted a few seconds. I flew the airplane and talked to ATC while the First Officer pulled out and read the engine limit surge checklist. I declared an emergency and told ATC that we needed to return. I sent an ACARS message to Dispatch and had the First Officer advised the flight attendants and the passengers of our intentions. All engine indications were normal by this time so we left the engine running as per the checklist. Descent and approach were normal except for a slight airframe vibration. On short final at 1;000-800 FT; the Number 1 Engine again started to surge. Landing was imminent so we continued to a smooth landing. No reverse was used. Taxied off the runway and shut down the Number 1 Engine. Taxied to the gate and parked.
B757 flight crew experiences high EGT and engine surging climbing out of 4;000 FT. Checklist procedures are complied with; an emergency is declared and the flight returns to the departure airport.
