Hello and thank you for using JustAnswer. My name is XXXXX XXXXX I will do my best to help you with your Kia problem.

The P0440 code is for an evap leak, this could be a bad gas cap or a faulty canister vent solenoid, this would not cause the lack of power.

The P0171 is a lean code. Combine the lean condition and the lack of power and it sounds like low fuel pressure due to a failing fuel pump.
