=== Clean Your AFM ===

This may not be the most fun, but your AFM is more than likely more than 2 decades old and chances are it hasn't been so much as wiped out in that entire time. That would be a rather significant layer of buildup in there, and no doubt has to be adversely affecting your performance. There is a small plastic piece protruding from the side - this is your Air Temperature Sensor; be sure it's clean and free of buildup, but be sure to refrain from damaging it. A cloth or paper towel should be sufficient for cleaning the internals of your AFM, but if more is needed, brake cleaner is useful for its lack of greasy film and quick evaporation. Be sure to wipe any excess cleaner away, regardless.
