 Okay, so here's what could have happened. They most likely said it was due to the fact that, you know, it was the wrong filter installed too much air. But what I would be concerned about, there is a good possibility that when you replace the air filter itself, that a little bit of debris could have passed through and ended up on the mass airflow sensor. I mean, I've seen where a little bit of cottonwood could be embedded on it or even over time.
