Default Throwing codes

Alright, so I code scanned my truck for old codes, and it threw the code PO171 and PO174. These are both lean codes. Does anybody have an idea of what this could be?

Funny you say that. The intake gasket has a small leak and I don't give the money to purchase a new gasket. An I need the truck inspected, but that code is coming up so I dot know if I'm gonna be able too. I reset it before but it's back again

If you clear the codes then the monitors will be incomplete Idk about there but here you will fail because of that

Doesnt take much...there is unmetered air going into the engine and thus the lean codes
