The last few months I've been getting the p000b code every 3 weeks, but now it's becoming more frequent than that. Additionally in the last month, it's gotten very cold in New England and sometimes at idle the engine would become very lumpy and feel as if the cam timing had completely reversed; it would go away if I turned the car off and on again, or if I gave it some gas. Some times it would then generate a p000b code minutes afterwards, sometimes not. A few days ago I got fed up and reflashed my stage 2 tune, and the idle problem went away. I drove a few hundred miles and the p000b code came back. Now I swear I hear a ticking noise after I let the engine idle (could definitely be paranoid...), and I'm worried that I could be causing engine damage the longer I let this problem persist?

The p000b code seems completely random. It's not when I make hard pulls, it's usually when I'm just driving along; sometimes it came up after the engine got super lumpy at idle. Is there any ways I can diagnose this myself? I've seen the Subaru bulletin for this issue and read the nightmare horror stories on this forum. Realistically my choices are below:

1. Have my guys at Monroes put the stock header back on, reflash the factory tune, pray the p000b code pops back up, and then drive 3.5 hours to the dealershit where I bought the car. My f*cking factory warranty expired a few days ago. Hope they don't give me crap for the ECU flash counter, and somehow cover the cost of the work.

2. Have my guys at Monroes provide a sanity check, then take it to a more local dealershit leaving it stage 2 and forget about the warranty, and then just pay out of pocket.

3. Just keep clearing the code every couple days lol.

Let me know if you think there's anything else that could be contributing to my problem that I can check into. Thanks!

What is "Monroes" ......??

Since I don't know anything about it ..... I would suggest you disconnect the battery, drink a beer, reconnect the battery ...... to see if the ECU had just hiccupped and will right itself.
