    I agree on the O2 sensor, but since I had unplugged it ~6 hours before that I'm gonna give it a few drives and see if it disappears.

    I've searched for leaks 3 or 4 times now and I can't find a single thing.

    If nothing else I'll just go put it through the dealership's window and leave it in someone's office.

    Well they were things I intended to change anyway as I'm near 75k miles. I can't do any sort of logging with my V1 unfortunately.

    What else would cause me to hit a boost cut just from a simple flash and then have the problem remain at the same rpm every time whether stock or stage 1?

    I'm willing to check out anything that may be the problem.
    Download romraider, take V1 cable and plug it into your laptop, start logging. Worked for me but not everyone has the same luck.

    Have you done a smoke test? It will find the leaks.

    I'm looking for a shop that'll do it for me. As I lack the proper equipment.

    Maybe something didn't go right when I had to put it in test mode to flash?

    Holy hell, on my way home just now it happened again ~3k rpm and it felt like I got punched in the stomach. Then it puttered for 5 or 10 seconds and went back to the way it's been the last few weeks.

    Got another CEL but I was almost home so I'll get that checked tomorrow.

    Guess that's what I get for divorcing the AP and my car.

    No cluster light for the parking brake either. She's falling apart lol

    If you're getting seamingly random electrical issues, to me it sounds like an O2 sensor or sensor fuse or something.

    It also reminds me of when I installed an UICP on my last Evo...it had slipped off and the car went nuts. The only way I could really limp back to the garage was to unplug the MAF. The car wasn't normal but it was driveable.

    When you used the AP, you did unplug the 2 green cables when you were done right? Any chance you pulled too hard or something?

    But given that you're having worse and worse symptoms I would just bite the bullet and take it to a shop or even a dealer to have them figure it out.

    Oh yeah I made sure to unplug the test connectors...

    Where would one find the sensor fuse?

    I fully intend to take it to the dealer once they can get me in :-)

    I do have 1 connector all lonely under the driver's side dash but there's not enough wire movement there for it to remotely plug into anything.

    Looks like your flash block connector - it doesn't plug into anything unless you are reflashing your ECU.

    I was under the impression that you need only connect the green test connectors on an '06.

    Ah, I didn't know that. Maybe someone with an 06 can chime in. I still doubt it is anything to worry about.
