P0133!?!?!?
Got this today? Should I be concerned? Usually get P0140, but this came along with it tonight...
Starting to get sick of all the SES i've been getting with the X?
Any insight would be great. Exhaust leak maybe?

I run a Long o2 DP from Ultimate racing as well as RRE Rally TP and Ultimate racing catback (TBE). I also run an ETS Exhaust Manifold. All these were done quite awhile ago (Dec, January time). All gaskets were replaced @ that time as well. Should I baby the car for a bit until I can have it looked at? This is the first time I've thrown this code. Im tuned by Bryan@GST.
This is starting to erk me with all the SES's i get with my X. Never had any issues with my STI, and it was just as built as my X's is now...

Hi Tephra!
I'm getting the same code on my X. I replaced the front O2 today with a Denso 234-4116 (which i believe is what comes stock) and had to code come back within 45 minutes of driving. All I have on the car is an aftermarket intake, 1000cc injectors and an ecu flash (Tephra tune). Thankfully I was able to pass inspection last week due to the genius of some Evo guru(s) out there
It's a bit concerning how lean the afr gets during idle though. The car leans out the a point where it wants to die or actually stalls. While driving things seems fine, but at a stop it's a gamble. I'm not sure to where to look next as i've been digging through the forum posts and have seen similar problems but no verified solution. Maybe exhaust manifold leak? Maybe crappy aftermarket intake? who knows..
I have a more detailed forum post here: https://www.evolutionm.net/forums/ev...l#post11920250
Any of your guru insight would be greatly appreciated!
