Also are you still doing BJJ? I did it for a little bit but ending up stopping because I had to prioritize my finances. I plan on starting back up sometime this year.
I will definitely try to remember to post back once I get it figured out.

I've had the overlays on for probably close to a year an a half now. They've held up very nicely! Actually had a local tint shop install them for about $75. I'm sure it's something I could have done if I had decided to take the time to be a perfectionist about it but I preferred to have a professional do it. He said it was a pain to work with and I took his word on it. Definitely worth the cost of install IMO.

I get to train BJJ occasionally but not as frequently as I'd like. Between being a full time student and working I'm lucky to make it once or twice a week. Definitely something I'll get back to more frequently at some point in the future.

Clear the code with an actual code reader. then see how long it takes for the cel to return. If you can drive it for over 50 miles without the cel returning then you can pass the inspection. Just to help kick the can down the road lol

UPDATE: Took my car to my mechanic today. He checked the codes and only the P2A00 code was still there but it wasn't active. He said it was most likely a sign that an O2 sensor could be starting to go bad but that it wasn't anything to be concerned by. He cleared the code, test drove it, and the light stayed off. Very thankful that what I was concerned might be a costly repair ended up costing me nothing but a trip to the mechanic.

After installing my motordyne art pipes I got p1148 & p0031. Went back to check my work and had an exhaust leak. Fixed that clear the codes but now only p1148 keeps coming on after a minute of clearing it? Any ideas on what it could b

Right now, I have both the p0037 and p0057 codes on. I installed two OEM converters (I previously had test pipes) and changed both my downstream O2 sensors. After ECU reset, the CEL comes back on. Two things I noticed but didn't really pay much attention to was that my PCV hoses are disconnected and on a cold start, my RPMs start at around 900 and then jump to 1,300-ish within a second or two. On a warm start, my RPMs are at a consistent 700, which is normal (I think). Do you think the PCV hoses may be the cause of the CEL light illuminating?
