I know there is bank one, bank two, downstream and upstream but the code that came up could be many things. The code was p0172 (car running too rich) but a lot of G owners are saying that it is my O2 sensor and it is bank one in my situation. I could see that being the problem because my car is tuned and I have a flame tune on it also so my sensors are probably cooked. Now should I be worried about the sensors that are plugged in to my test pipes and is that even a thing or are they plugged in somewhere else? Someone please just break it down for me really simple and easy on where my sensors are plugged in? how many I have so I know how many sensors to buy?

One O2 sensor before each cat and one after each cat. Your flame tune is killing them.

Here they are:


O2 Sensors

BULL

So 4 exhaust sensors: Bank 1 & 2 Airfuel sensors pre-cat
Bank 1 &2 Oxygen sensors post- cat

And like stated previously you're killing the sensors.
