This is so frustrating. From time to time, ofter the trottles get stuck and im only able to use one throttle. Example...left throttle leaver will not move, but the right lever will move. any suggestions...

is this with a controller that has two throttle levers?or are you using <shift><e> <1> or <2> to switch between engines?--

press E 1 2 in quick succession and you should have control over both engines again.
