I do have a K&N air filter on it. Don't know if that matters or not.

Good morning,
You have a MAP sensor, not a mass airflow sensor.
The difference is the MAP measures pressure or vacuum and the mass airflow measures airflow.
K/N is a bad idea. It is never recommended for any computer-controlled car. There is no increased performance from it at all. The only advantage is that it does not implode under heavy acceleration.
It also has oil in it and it goes into the intake and contaminates all the sensors. If you had a car under warranty and a dealer saw a K/N filter, they would not work on it and void your warranty for the engine.
What is the issue that brings you to this question?
