Tom,
Try hitting the "E" key and then quickly the "1" then "2" (and if more engines..."3" and then "4") keys. That should reset the throttle controls to all engines.
That is a weird "bug" with some aircraft.
And sometimes...... particularly in multiplayer when using the "chat" box.... you accidently hit the "E" key and a number when you are NOT in the chat box.
best,

And it's as simple as that! haha now I feel stupid :-[
Thanks for your help john
