only one throttle works

Hi,
When I use my gamepad to use the throttle, only one lever will move. The same happens when I use my keyboard. So it cant be a problem with my gamepad. It also happens to only a few planes.
There has to be a key command to solve this problem, but I dont know wich one to use. I checked the command list. I saw you can press 'E' to select engine, but that wont work. I even dont know what it really does!!
Does anyone have a clue?
Thank you very much!!
