Narrative:

At FL370 noticed an right 'eec altn' lite. Followed QRH on descent. After following QRH right engine N1 and egt began fluxing. Fuel flow slightly higher. As I pushed throttle up fuel flow and N1 continued higher readings than left engine. Greater thrust out of left engine evident. With no further relief in QRH and at 13;000 feet getting low on gas and unable to control right engine ( fuel flow at approximately 11.2 w throttle at idle ) left engine at idle. Unable to descend due to high thrust out of right engine we requested priority handling and shut engine down. Vectored in IMC to ILS runway xx.
