I have a 2005 Explorer 4.0 that goes into efsm every time I drive it. There is a noticeable difference in power and gas usage but the truck operates fine. Get on the interstate and goes 80+ just fine. I have taken my scanner to it and no codes. I even took it to autozone and no codes. I dont know what or where to start. I have replaced the ERG, ignition coils, map sensor, throttle body and throttle body position sensor changed the oil. Im now having some issues from the transmission but again no codes. Help!!!
