if you go back to page 1, you will see the 2 red circles in the picture. You disconnect those parts. Removing the sensor with a Phillip screw driver untighten the metal bracket. You should unhook the pressure pipe connected to the valve by squeeze the lock and twist. You remove the EGV (I think that's the name of that valve) by unscrew the 2x10mm nuts. You should be careful unscrew and screw them back as the space is limited there. You should inspect the pressure pipe to ensure no air leak as the air into the valve blows air into the engine block.

I cleaned the secondary MAF with MAF sensor cleaning solution from AutoZone. I cleaned the valve with brake cleaner (might not be the best option, but that's all I have in stock). Hope this helps.

So far, the SES light hasn't returned yet. Knock on wood..
