My engine light came on and by process of elimination I'm trying to correct it. So for I changed the gas cap (OEM), and rebuilt the DISA valve based on a thread here (using X8R parts).
A rattle under the hood was corrected and acceleration improved. My mechanic hooked up his scanner and P1415 came up. My next fix is to clean the Mass Air Flow Sensor with MAF cleaner.
...Has anyone had success doing this or should I just replace it?

Cleaning mine with Maf cleaner sray completly killed it, new oem Maf solved my problem. DO NOT be tempted by cheap ebay Maf's they rarly work right or last long, buy cheap pay twice as they say. Stick to oem brands Bosch or Siemens.
