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.

After doing some more research I am going to cut the honeycomb out of another MAF and see if that fixes this. Also got to replace the thermostat and lower hose, as I was installing this I kept getting antifreeze on my hands and quickly realized that problem as well. Busy weekend ahead hmy:

Are you tuned? If not the atmospheric bypass may be causing you some issues.

No, but plan to be quite soon.

Seems fixed after cleaning MAF this morning

If anyone cares how I permanently fixed this. Got the idea off a youtube video. Drove 40 miles today with no CEL, used to come up within 10 minutes.

I searched for it last night and couldn’t find it. Here it is: https://youtube.com/watch?v=U-r9kXxXt_4

With mine I made sure to save the plastic and metal mesh versus just the plastic. May not make a difference.

The guy in the video found the information he used here on CruzeTalk:
