How do I keep the mixture from leaning the engine (without me touching the handle) and killing it?

Question

Pretty much every time I use X-plane now, the mixture control goes lean (without me touching it) and the engine dies. How do I fix this problem?

Answer 1

There could be a lot of things affecting the mixture. If you have an axis on a joystick, etc assigned to it, it could be incorrectly calibrated or a duplicate assignment. There could be a plugin affecting it. We would need a lot more details to investigate, such as the log and maybe a screenshot of the issue or the joystick settings.
