So my check engine light came on the other day with p0171 and p0174. So I checked that rubber 90 on the back of the throttle body and it wasn't cracked or damaged at all, so I put it back together and cleared the codes.

So today I plugged my tablet in and ran torque to watch the fuel trim readings (pics below) and I'm not sure if the readings are good or what but my CEL came back on when I was on my home later and these codes were stored, and I have no clue what they mean...
