I had a scan done on my above mentioned Expedition and mechanic determined I needed to replace my mass airflow sensor. He said Ford no longer makes them and said I really needed to go with a motorcraft xl3z12b579ba. He said to google that part number and it will come up. He said they are roughly between $400-$500. I found other after market brands that fit my vehicle that were much less expensive. Can anybody advise of a particular one that is less expensive but good quality. Thanks!
