I can't seem to get idle back to normal. Cleaned IAC, throttle body, mass flow. Any ideas?

HI there

The code P0171 is for a lean fuel mixture. This could be due to an intake air leak on bank 1. This will also cause the high engine idle as well. 

the other two codes are related to the bank 1 front O2 sensor. This could be the result of the intake leak or a problem with the sensor itself.
