I've got an odd feeling the bank 1 lambda sensor or MAP sensor may be faulty, but again no faults are being read... any advice please, TIA

Buy a can of intake/carb cleaner and clean the maf sensor carefully with cotton wool and a spray of the cleaner first and see if that helps. Also may as well clean the pcv valve and the throttle body while you are doing it.
