U must remove the entire dash assembly and then the heater core housing which is part of the air distribution box, time to do the job 10-15 hours.

O171 MAF (Mass Airflow Sensor) Just try cleaning this part it usually solves that problem without having to buy new part.
0174 Both are mass air flow sensors. The other problem can be a vacuum leak Check PCV valave and all vacuum lines. Also make sure fuel filter and fuel pump are working correctly. You can clean the MAF with some brake cleaner make sure it is dry before you install it back
