It says that it's O2 bank 1 sensor 2 signal swapped w/ 02 bank 2 sensor 2?

WTF? What would cause that? I recently had new RR catless DPs installed by Rassmusson BMW, they replaced one of the 02 sensors because the threads on the sensor was stripped, and it was fitting kinda loose........

The SES came on this weekend, along with the other code I've been having every now and then, which is the P114b and P2270. I'm sick of this, please chime in if you have experienced these codes and let me know what might have caused them........

Also, this past weekend when I was taking her up high around 100 mph or so, that's when I felt the small hiccup/stutter around 5k rpm in 5th gear. It felt restrictive as far as power distribution goes, bogged down if you will.

I've read somewhere that another forum member experienced the same thing when in high mph and rpms, but couldn't remember the thread or the name of the member........

Anyway, I thought that was a sign of HPFP going out, because the power that use to be there around that speed and rpm is no longer there!! It felt stock-like.......

Please chime in

Thanks

Doesn't sound like a downpipe code. P0420/P0430. Are you having any rough starts yet?

Well, I did notice a little bit of a hiccup if you will. Meaning, when I start the car and let it sit and idle until it drops to 600 rpm, before it reaches that, the needle kinda goes down and back up just a little bit (about 100 rpm or so) and then it goes down to about 600 rpm......

What does this mean? Is it my HPFP going out?? I hope not........

Please chime in

Thanks

Well, the dealership I go to is mod friendly. Plus I've been dealing with the head of their Motorsports department, who is a nice guy. I've also been honest with him from the get go, and vice versa. So he knows my situation.......

I just don't think I can trust anybody else with my car anymore. Besides, there's not really any shops in Portland that knows and are experienced in working with the new E90s.......

I have a shop in Vegas that does good work. That is who installed my friend's downpipes.
