Posted to Ford Driveability on 1/8/2009 9 Replies

replaced maf sensor a couple weeks ago and light came back on two days later...didn't know if someone had been down this road before and could tell me what to look for...smoke tested vehicle and could find no intake leaks...any help would be appreciated.
