Narrative:

On takeoff roll I initially advanced the throttles to EPR of 1.05. With both engines stabilized I continued to advance the throttles to the climb detent. Both engines initially advanced normally; but when they both reached approximately 1.15 on the EPR they stopped advancing. The EPR gage was commanding a much higher EPR somewhere in the range of 2.9. After approximately three to four seconds and the engines not advancing we decided to abort the takeoff. We pulled off the runway and taxied to a point where we could investigate the problem. The captain contacted maintenance and with their concurrence we returned to the gate.
