Hey guys, so my EML has come on again (has previously probably coming up to a month)   Had my code read and was to do with air something or another. The garage said not to worry, cleared it and said come back if it does it again. They said it's probably a dirty sensor or at most a spilt hose.   So driving back last night my EML light makes another appearance so thought id give cleaning the Maf a go. Just wondering some pointers as to how to do this. Remove it, clean it, clean with what etc?
