    Remains to be seen I bought the tires and wheels the rest came along
    Just what did you delete THE EGR system or the balance shafts?

    Never forget with codes it is the complete circuit. The heater had failed in the O2 sensors you removed?

    A tripped Heater circuit code most likely is the cause of the PO171 code.

    The PO401 since I never did a EGR delete I have no clue how to generate a false signal to The ECM.

    Good luck!
