Narrative:

Aircraft had had several write-ups regarding the left engine eec being inoperative and I believe it was replaced the day our flight operated. On takeoff roll with power set and about 110 knots I felt the plane yaw to the left as if we encountered a crosswind gust; but there was also a change in engine sound and then I noticed the N1 drop about 10%. It recovered to just about takeoff thrust only to roll back again. At about 130 knots I elected to reject the takeoff. We didn't declare an emergency as there were no overheat or other abnormal indications. We cleared the runway and contacted maintenance after reassuring the passengers that all was well and were told to have the fire department check our tires and brakes for any abnormalities. It was very close; so we taxied over to the firehouse where the fire commander checked out the aircraft and found nothing wrong. We then taxied back to the gate and parked making sure nobody was allowed near the main gear.

Title: B767-300 flight crew experiences an engine surge during takeoff causing a loss of thrust and a rejected takeoff at 130 knots. The EEC for the engine in question had been replaced by Maintenance just before this flight.
