Exclamation 4.0 Scan Codes

Have code PO455 and PO171 on my 1998 Ford Ranger. My truck has a 4.0 backed with a manual transmission, packaged in a single cab. I would really appreciate any information I can get in the repair of these codes with spending $1000 in parts without the cost of my time and shop bill. Through extensive research, I've learned that both codes are thrown due to evap, fuel, air intake, and exhaust system anomalies, but I could not find one, central, point to actually fix or replace that would "cure" both codes and remove my check engine light for longer than a scanner erase of the vehicle codes. Help needed, thank you

"The cost of your time" working on your own truck?
