It tells me bad o2 sensor and says bank 1, but i need to know if it is the front one or the back one

A good scanner should tell which one is bad but you might wind up replacing all of them

Check which side of your engine has cylinder #1. That side is bank 1. Bank 2 is the side opposite of bank 1. So bank 2 is not always passenger side. And since you seem to have extra O2 sensors, I would replace the other upstream and see what happens. Also the mass air sensor can give a trouble code issue to the upstream 02 sensors. Good luck. I've struggled thru this myself.

disconnect the sensors cancel the codes start engine if the codes don't come back replace sensor

bank 1 is the side cylinder 1 is on.sensor 1 is the first sensor in the exhaust on that bank from the manifold.cylinder 1 is the most forward cylinder on the motor when you look across the motor at the front of it to see which head/vlave cover is farthest forward.

If the O2 Sensors are original,you could just change the front 2

The ones closest to the engine.

Any other issue you need to actually diagnose, as codes
are for just that reason

They don't ever tell you to replace anything

Running rough is more the O2 Sensors

Plugs
MAF Dirty
Vacuum Leaks
Ignition Coils going bad

It means you have a bad oxygen sensorThe way you know witch one is bank 1 is the cloest o2 sensor to the front of the vehicleits in the y pipe likely on the drivers side that would be bank 1 sensor # 1 if the closest one to the front is on the other side then that would be bank 1 sensor # 1

To what? It is located in the exhaust pipe bolted to the rear manifold. Near the firewall

Bank one is on the side of cylinder one. Cylinder one is typically on the driver side. Although, you have to be careful here. Just because the code mentioned the O2 sensor doesn't mean the sensor is bad. For instance, a code of P0171: sensor indicates lean, bank one sensor; one is not a bad sensor. That is a good sensor telling you that the engine is running lean on bank one. If you get a different code, then it could the be the sensor.

p1133 - o2 sensor, Insufficiant Switching, Bank 1 Sensor 1.
p0131 - o2 sensor circuit, low voltage, bank 1 sensor 1
p0171 - Lean condition, Bank 1
p0300 - Random Misfire

I would be looking at the front passenger side oxygen sensor for issues. It may be bad, it may not be plugged in, bad wiring at harness.

The random misfire may be symptomatic of the o2 sensor problem.

You have a broken wire at the connector for the 02 sensor. the brake may be inside the shielding.
