So as the title states, I installed a cold air intake today (one of the longer ones, previously had a short ram) and now I was almost immediately met with a P1101 code. At the same time I also did installed a BNR (Forge) atmospheric bypass valve. There were no codes before the install. Everything seems to run and perform as expected, but I have a constant CEL on and this code. I did perform a quick search of the forums and it seems to be pointing to the MAF, I checked it and it is plugged in and appears clean. Anyone have some more insight?
Edit: this car already has the PCV fix kit V2 installed and has ran fine with it for around 1k miles.
