    Yeah it's still broken. I have a camshaft position sensor I can swap out so I'll try that. Won't help but it's not much effort so why not.

    If all you're changing is whether the MAF is plugged in, then there's really just a few components that could be causing the issue:
    MAF - Bad sensor or wiring - See question above
    ECU - Bad ECU - possible
    02 - Bad sensor - Already replaced, so should be ok.
    Piping - Leak - Checked already, so should be ok.
    It's looking like the ECU is getting closer and closer to being replaced. Once I convince myself that I can do it. Well and acquire one.

    It probably is the ECU, knowing me I screwed something up when I tried to flash it.

    That's another code related to all the things you've already reported. It doesn't help diagnose the problem any better, sorry!

    There just wasn't any tension on the spring. Guess I forgot that part lol.

    It's all well and good. Learning View reports no DTCs again, yay.

    Though I would actually like to see a CEL so the car would tell me what's wrong with it.

    There's a lot of guys like me and Donkey that are pretty hardcore tuners and car modders so if we can't figure it out, even from internet posts, then you've got a really hard problem. He's stronger on Subarus I bet but I'm probably stronger on a wide bunch of cars. But it just doesn't make any sense. I'd love to see/drive the car in person. That would help me a lot, but that's not going to happen.

    Well I take that back maybe I could. I'm heading to Cali some time in the next month or two and passing through your area.

    That's a bad ass offer! Though I would hope I don't have to take you up on it... I hope it's fixed soon. Though it has been a month and a half already.

    Any way to test the ECU without needing another one to swap?

    No, there's no way to test a bad ECU short of swapping it. It's the brains of the operation and runs the show.

    Well there is a way to test it but it requires really knowing how to hack an ECU.

    He says an STi MAF helped a bit but didn't totally fix it. Aren't they the same part #?

    To the best of my knowledge, yes, all 2.5L engines use the same MAF.

    That's what I thought. Just adds to the confusion.

    Dealer says both cats are bad, will be taken care of next week. Factory warranty FTW.

    At least if it doesn't work it's free.

    What is exactly is "bad" about them? How is under warranty if it's a 2006?
