my car for that 11months and i'd say 11k or so miles has ran fine... Not one problem at all to speek of... Im just so sick and tired of havin the light on its not even funny and my inspection is due here in about a month so i gotta get it takin care of. As for me im gunna fix the exhaust leak and hope that does it. This is one job i really didnt wanna have to do due to how much of a pita it is gunna be. How much did u pay for the maf??? Did u buy it stright from ford??? I bought a used one and maybe if this fixes ur problem i will break down and buy a new one and give that a shot as well. I did hook up a scanner to my car and tested the volts and what not from the maf and it looks fine so i dont believe this is my problem. But with these 2 codes my car has ran fine for as long as i've had it. It may not get as good as gas milage but honestly i wouldnt know cuz i've never owned the car with the codes off .... ya keep me posted and i'll do the same. Good luck lol
