    P1175 means fuel trim adaptation additive bank 2 malfunction. The common possible causes of this trouble code are defective fuel injectors, vacuum leaks, faulty EGR and/or defective oxygen sensor. This link might help you

    Thanks for your quick response, I changed the Air Flow Sensor, now I will try on the vacuum leaks, oxygen sensor and see what happen before going to the EGR or injectors.
