My check engine light came on, so I took it to adavnce auto parts to get it read and these 2 codes appeared PO101 and PO171, I know it has something to do with the Mass Air Flow. I cleaned out the mass air flow sensor but these codes still appear. What do i need to do, to get rid of these problems?

my truck is an 2007 WT Silverado. New boy style
