Split of thrust levers during cruise

Hello guys!

I have a question about operation of autothrottle system. After engine#2 replacement we observe split between thrust levers. A/T doesn't disconnect. Can condition of engines be the cause of split? Because engine#2 after overhaul the other has worse characteristics.
Thanks in advance

yes. When its a classic you will have a split if you didn't properly do the partpower rigging, vsv and vbv rigging, accell and decell test etc. it is very important to do the adjustments to match both engines.
