The engine warning light comes on with a message that says engine operating under reduced power what could be the problem? Already changed the airflow sensor ran good for 4 days then message reappeared

That message is associated with a problem with the "drive by wire" system and gets quite complicated to diagnose. The first step is to get the actual code numbers but it may require some in depth testing after that.
