Do you have the same issue if you follow the OP’s steps to reproduce it?

Yes

Provide extra information to complete the original description of the issue:

Also when engines are runing, If I go to idle looks like aircraft loses power making hidraulics for example and taxi lights to turn off. I remember to fly this a/c a time ago with no issues. Please fix it, I love this plane so much
