    another car niggle ..

    over last few days the car has developed a niggle .. it has started intermittently missing in low gears at low revs more prominently...when in say 4th cruising along then put foot down it misses as it picks up ... any ideas ? air getting in somewhere maybe ?

      Have a read on this and then start your investigation. Start with the MAF.

          ABY, AAN or ADU, the missing issues are all the same. I wrote that for the AAN but it applies to the ABY and ADY equally.
