X5chemist will become famous soon enough
Are P0171 and P0175 the only codes now? If so, I don't think the MAF is causing them. The second bank is getting too much fuel. The extra fuel is causing rich fuel trims. Have you OHM the injectors? "This code will set when the ECM can not compensate for the amount of air or fuel required to return the air fuel ratio back to the set parameters." It's not happy with something on bank 2. Cylinders 4,5, and 6.
