after cleaning it, reset your ecu by unbolting and disconnecting the negative terminal on your battery for 5 minutes.

Your car will feel completely different after you clean the MAF. Like it has new life.

I've cleaned it twice or three times and didn't make any difference. It goes off after I clean it, then comes back on in a day or so.

Jen there are 2 spots on the MAFS you're supposed to clean, the air temp probe and the little wires in the canal. Here is the air temp probe:

Here are the crutial wires that need to be cleaned. These are the ones that are probably really dirty and what caused your check engine light P0171.
