Hey guys, I might understand what needs to be done, but Im not really sure.

I have a 2014 V6 with an Airaid CAI, BBK LT, BBK X-Pipe, Pypes Mid muffler Catback

The problem is that in neutral, it tends to drop rpms to like 100 then shoot back up to idle, and sometimes it'll even stall. I have done the battery relearn. There is a CEL and the code pulled is P0131, bank 1 sensor 1, which is driver side upstream O2. I dont think that's the problem, but Im guessing it just needs a tune.
If that's the case, it is bad for the car to keep randomly stalling? Currently I don't have money to tune... Until at least b'day or Xmas.

Thanks

fuel filter maybe? a lean condition may bugger up the O2 sensor.

It could be that the PCM is having trouble correcting for both the intake and exhaust. Does it stall out with the stock airbox installed?

Do you have a tune at all right now?

I still have the factory tune.

I had a full exhaust makeover first before adding the CAI, and it would still drop RPMs but never actually stalled. When I installed the CAI, it started stalling, and only did so twice. Once at like 2:59 AM in Indiana and another time at around 10:00AMish in Georgia. Both within like 30 minutes of starting up.

It hasn't happened in a while, but the RPMs still decide to drop. Any suggestions?
