Not calibrated correctly
The mass airflow sensor is reading higher Grams per second than what is actually entering the throttlebody. My scan tool shows that it’s reading 67 8 g/s where it should only be 3 1/2 maybe four also the air intake charge thermometer that has built in with the mass airflow center is reading -40 with key on engine all that is not correct, I will be returning and asking for a refund. Sometimes these parts are very hard to find that work correctly on your vehicle. Ford is very picky on the sensors that you install the best thing to do is buy Motorcraft from the beginning and you will have no troubles .
