Can a mass air flow signal too high actually be the maf as my car stalled yesterday and threw fault code for maf signal too high usually it's over boost or lambada bank 1 but only code was maf? Could this be my issue connections checked /sprayed with contact cleaner and seem ok! Maf is genuine bosh and Farley new my actuator preload is set at 0.4 bar and holds perfect my boost gauge hits it's original position maybe a tad less but I still normally hit over boost and then lambada bank. 1 insufficient flow? Only code when car died was maf signal too high thought it was map only related but am leaning towards a new maff as well possibly?????
