Just fitted my dawes device and dawes afr and geting some strange readinds on tick over just red light flashing bliping the throttle lights up to blue then goes back flashing red, on wot i only get red light in fifth gear car. car seems to be holding back only running 0.9bar in fear of doining some damage. if the maf sensor is on its way out ie low readings on engine check light would this cause the lean running.
