hi there i have a 1998 subaru legacy GTB and i have the codes 23 and 24 which are afm and the iacv well i brought a replacement orange are cleaning and resetting ecu failed to clear it and i reset the ecu today and put the replacement in and i went for a boost because my car has been down on boost used to be at .9 - 1 bar of boost on secondary and now only .7 and the codes are back again
could it be possible that my iacv is causeing the AFM code or is it just down to bad luck that 2 are faulty
also tried to clean the iacv but have lack of tools and i couldnt reach the bottom bolts of the unit without removing top mount and dont have the spare 5 hours to put it back on again
