possible BOV issues
 

hey has anyone had any problems with the HKS SSQV BOV? mine has been on car since i have had it but im now experiencing poor idling, garage suspects vacume leak i have checked all hoses.

just wondering if this could be the cause.... its not plugs, i have used subaru engine cleaner, an fuel system cleaner.

i did have on mine at one stage and it used to backfire every so often took it off and bought a aps twin vent bov never had a problem since.

I've got one on my STI, no dramas as of yet.

weird took it apart no sign of problems put it back together, and its runnin sweet again....
