    P0171-Powertrain System too Lean (Bank 1)

    i Clean my car Throttle + Sensor
    MASS AIR FLOW METER SENSOR
    and clean Injectors after opening the Fuel Rail.

    now the Error is their for about 15 miles driven.

    Live data can get by Torque or Mini VCI how to find where i need to look for problem or where shell i look.
    Thanks
