A faulty MAF sensor can cause a variety of issues, including decreased performance, rough idling, decreased fuel economy, and engine stalling or hesitation. When replacing a MAF sensor, it's important to choose a replacement designed for your specific vehicle and to follow any specific installation instructions provided by the manufacturer.
