Have either of you ever received a recall notice from Subaru for your o2 sensors or reprogram of the ECM? I had that code several times and once the dealer replaced the cat, it went away. I had the standard mid-pipe but Stromung rear box. I've also heard that that setup will throw that code frequently, but its meaningless after a while.
Oh, my pe0065 is currently off. I took apart the solenoid behind the power steering resivoir and cleaned it. Seems ok now, but I'll give it a few hundred miles before I declare it fixed.
