During the process of replacing the air filter, the air intake hose was torn. It already had a long crack in it and it was very stiff. The replacement was affordable and I am hoping the CEL P0171 code about lean fuel will resolve given proper airflow around the MAF sensor. Update: Just checked with David and the Engine light did not come back on and they just drove back to Cullman.
