Hi Dorian. Thanks for contacting us today. The mass air flow sensor itself is an on or off type of component, meaning it either works or it won’t. It doesn’t take time for the sensor to ’break in’. The issue that can take time is if an error code is stuck in the ECU, has not been removed - yet the component is replaced. This will cause the ECU to receive false data from this component and continue to display symptoms. The other possible issue is that the electrical harness connected to the MAF is damaged. You should probably clear all OBD-II trouble codes or have a professional mechanic come to your location and complete a check engine light inspection for you for starters.
