I have been experiencing this issue where the throttle axis arent in sync. Lets say I have a flight, takeoff and everything is just perfect and when I disengage the autopilot for landing, throttle for engine 2 stays stationary and my input only works on engine 1. (Always throttle for engine 2) I might add that my quadrant just works fine, this aircraft is the only one that does this, and this is not true on every flight, but 1 in 4 flights. This is rather annoying and needs to get fixed.

Have you incidentally pressed "E,1" in flight? can you get it back to work by press E then 1234?
It's an old FS/P3D issue I got at fs9 days, E is for selecting engines and the number came after press E is select what engine is selected.
And if it's the case, I recommande to delete the E in P3D's key assign.
