Hi everybody, Its my first time on here so forgive me if its in the wrong place or topic area. I need help with my 6 it has all of a sudden started hunting at idle and through the revs, It runs smooth and not rough but constantly hunts. I found a crushed pipe coming from the pcv valve which went back to its original shape when the engine was turned off so I replaced both the valve and the pipe but to no avail. There are no air leaks anywhere and no faults when connected to a reader. There are certain things I can do to make it stop hunting which includes restricting the airflow through the filter housing by putting my fingers in it across the intake just before the MAF and it runs lovely. This is obviously not a permanent fix and could be putting me along the wrong path Don't want to take to Mazda @ £114 p/hour to Diagnose only. It has been to two garages so far and nothing. Anybody had this or any advise would be very much appreciated.
Fergie
