After installing a donor stock intake air box from a 2004 on my 2010 I cleaned the MAF.

I re-learned an important lesson which I saw stated somewhere on here. - replace the gasket. The one on the sensor I reinstalled was loose looking. Lucky I ordered a replacement (took a few days to come in) as I got my 1st Change Engine Light.

Installed the new gasket, cleared the code and magic - code stayed away.

Now I feel like a real owner (stated in Pinocchio’s voice). My first CEL.

 

also whenever doing MAF stuff, make sure those screens are in straight because they can wreak havoc on the MAF readings.
