So I decided to re-route the o2 sensor wiring to see if I could find anything and it turns out after the re-route I plugged the sensors back in, used some pliers to get it to click in properly and the code went away and hasn't come back. I am still stalling though, I believe it has something to do with the brake booster check valve. I get a hard pedal after sitting for a few days but since I got the car, the revs will bounce around if you hold down the brake after a cold start. It only stalls when I brake, moreso if the braking is hard and it only stalls when braking at low rpms. I think it might be pulling too much vacuum, anyone else experience this? Could possibly need a new ccv as well but I can't afford to replace the whole system at the moment.
