## Discrepancy

HNL FLT 26 - EN ROUTE OGG TO PHX.  AFTER TAKEOFF, THE CREW TURNED ON THE ENGINE ANTI-ICE AND NOTICED A POWER LOSS AND FLUCTUATION ON THE LEFT ENGINE.  THE ENGINE ANTI-ICE WAS TURNED OFF, AND THE LEFT ENGINE POWER PARAMETERS RETURNED TO NORMAL.  THE FLIGHT DIVERTED TO HNL AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE LEFT ENGINE ANTI-ICE VALVE.  OPERATIONALLY CHECKS OK.
