Description
The MAF measures the volume of air coming through the intake, which is a crucial metric that the ECU uses to determine fuel requirments. If your vehicle is giving you a MAF code, replace it immediately to ensure you get the best economy and performance.
It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails completely, the vehicle will stutter and stall as it falls into a limp mode.
One way to check if your MAF is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAF need to be replaced.
