What was found

IN CRUISE AT FL 360 WITH EPRS, N1 AND N2 BASICALLY MATCHED, NR 2 FF SHOWS ANYWHERE FROM 400 TO 1200#S HIGHER BURN THAN LEFT ENGINE. FF IS VERY ERRATIC ON RT ENGINE, BUT SEEMS TO BE VALIDATED BY THE HIGHER BURNOUT FROM THE RIGHT MAIN TANK. RT ENGINE FUEL FLOW TRANSMITTER WAS PREVIOUSLY REMOVED FOR FUEL FLOW FLUCTUATIONS.
