the maf is the mass air flow sensor, i think on your 1.8's its in your airbox, clean it with electronics cleaner and let it dry for a day, then drive it, be careful, very fragile

RE: P0131

well from what you told me that your cel came on after you put a new air filter in. so my guess is that you had an oiled filter and some oil got onto the maf and so now you need to clean it
