I think I found the solution by researching about F & N filters fouling the Mass Airflow Sensor. I ordered
two Delco OEM filters and no CEL for three weeks. Mine is a 2017 OR FWD with 40 k miles. I didn't start getting the CEO til almost a year after installing the K&N. I loved this car, but the CEL was trying my patience.
