    Default Maf cleaning

    My veccy threw up a maf low reading (or something along those lines).I was giving it a good thrash. Changing from 5th to 6th at about 95 ( private road of course! ) No obvious leaks so garage just reset it and it's been fine since although I have taken it a lot easier. Have been looking around the net and the fiat boys can clean their jtd's maf. Two screws and it slides out the housing and they clean it with alcohol and a cotton bud. The veccy one looks the same but it's a push fit. Is it possible to slide it out the housing or is it in there pretty solid??

    Did a quick search on here and the only thing I found was to spray it with carb cleaner. Seems a bit hit and miss??

    Not recommended to touch the MAF sensors with anything .

    Isopropyl is recommened to clean the MAF wires. Remove the MAF sensor from the round MAF housing/pipe and spray isopropyl over the whole of the sensor. Leave to dry completely and refit.

    That's basically the idea but those MAF wires down the bottom that you can't see are very fine. Over cook it with the cotton bud and it'll be new MAF time .

    As mentioned its a very fine wire smaller than a human hair sensing.

    You can spray small amounts of contact cleaner to clean it. But be carefully and leave it to dry naturally
