Once the MAF gets some abrasion from dirt, further cleaning doesn't help and you need a new one. Basically there's 2 small resistors deep inside the black tube of the MAF once they get scratched and scuffed enough they collect dirt much quicker. Even getting the MAF spray to hit them correctly is hard. The resistor you see on the outside is just a temp sensor. I remember seeing a youtube video close up of the damaged mafs before and after cleaning and it was pretty enlightening.
How many miles on your current MAF and do you drive through dirt roads a lot?
