Narrative:
First officer's leg departing. At 1000 ft AGL we had the left engine limiter message; an electronic engine control (eec) message; along with autothrottles disconnect message. We continued climb out without reducing thrust on the left engine due to high terrain. After passing through 17000 ft MSL; we got into the checklist for engine limiter; followed by the electronic engine control checklist. We operated the remainder of the flight with no autothrottles. We passed a message to operations with the maintenance message; and got a message back to proceed to our alternate. Approaching ZZZ; we received a descent from ATC from FL370 to FL290. As I brought the throttles back to idle; I first felt; and then heard; the left engine compressor stall. I pushed the throttles back up above 1.20 EPR or 65% N2. The compressor stall ceased. The captain and I discussed a game plan to advise ATC to keep a constant descent if possible to avoid needing to bring the throttles to idle. We also decided to start the APU in case we lost the engine during the approach or landing. Finally we thought we should have emergency vehicles ready in case we lost the engine. I flew the approach with normal landing confign and manual throttles. The captain spoke with ATC and helped monitor the engine and airspeed. At 30 ft AGL; I brought the throttles to idle and immediately felt the left engine compressor stalling again. As we touched down; the engine died and nearly simultaneously the captain shut the engine down. We taxied clear of the runway and were followed by emergency vehicles to parking.

Title: ON DEPARTURE; B757-200 FLT CREW ENCOUNTERS ENG LIMITER AND EEC EICAS MESSAGES. MANUAL THROTTLE RESULTS IN COMPRESSOR STALLS AT LOW THRUST SETTINGS. DIVERT TO ALTERNATE.
Narrative: FO'S LEG DEPARTING. AT 1000 FT AGL WE HAD THE L ENG LIMITER MESSAGE; AN ELECTRONIC ENG CTL (EEC) MESSAGE; ALONG WITH AUTOTHROTTLES DISCONNECT MESSAGE. WE CONTINUED CLBOUT WITHOUT REDUCING THRUST ON THE L ENG DUE TO HIGH TERRAIN. AFTER PASSING THROUGH 17000 FT MSL; WE GOT INTO THE CHKLIST FOR ENG LIMITER; FOLLOWED BY THE ELECTRONIC ENG CTL CHKLIST. WE OPERATED THE REMAINDER OF THE FLT WITH NO AUTOTHROTTLES. WE PASSED A MESSAGE TO OPS WITH THE MAINT MESSAGE; AND GOT A MESSAGE BACK TO PROCEED TO OUR ALTERNATE. APCHING ZZZ; WE RECEIVED A DSCNT FROM ATC FROM FL370 TO FL290. AS I BROUGHT THE THROTTLES BACK TO IDLE; I FIRST FELT; AND THEN HEARD; THE L ENG COMPRESSOR STALL. I PUSHED THE THROTTLES BACK UP ABOVE 1.20 EPR OR 65% N2. THE COMPRESSOR STALL CEASED. THE CAPT AND I DISCUSSED A GAME PLAN TO ADVISE ATC TO KEEP A CONSTANT DSCNT IF POSSIBLE TO AVOID NEEDING TO BRING THE THROTTLES TO IDLE. WE ALSO DECIDED TO START THE APU IN CASE WE LOST THE ENG DURING THE APCH OR LNDG. FINALLY WE THOUGHT WE SHOULD HAVE EMER VEHICLES READY IN CASE WE LOST THE ENG. I FLEW THE APCH WITH NORMAL LNDG CONFIGN AND MANUAL THROTTLES. THE CAPT SPOKE WITH ATC AND HELPED MONITOR THE ENG AND AIRSPD. AT 30 FT AGL; I BROUGHT THE THROTTLES TO IDLE AND IMMEDIATELY FELT THE L ENG COMPRESSOR STALLING AGAIN. AS WE TOUCHED DOWN; THE ENG DIED AND NEARLY SIMULTANEOUSLY THE CAPT SHUT THE ENG DOWN. WE TAXIED CLR OF THE RWY AND WERE FOLLOWED BY EMER VEHICLES TO PARKING.
