what is MAF?
2004 NISSAN SENTRA,ENGINE LIGHT ON FOR COUPLE OF WEEKS WENT OFF TWICE AT DIFFERENT TIMES STAYED OFF 24HR THEN CAME BACK ON HAD SCANNED SAID AIR FLOW SENSOR NOT WORKING,HOW SERIOUS IS THIS PROBLEM?
Mass Air Sensor, you can clean them. Go to youtube on how to do it. They don't fail often and a MAF code doesn;t always mean they are bad, you might have a vacuum leak.
