Fuel Too Leak (Bank 2)

In the case of it being cold, the ECU isn't controlling the fuel yet, it just uses a simple table to add fuel, once it heats up and the O2 sensors start operating then it will go into closed loop and you will see the numbers change as the ECU starts using feedback from the sensors to control the fuel mix. Take a look at the O2 mv readings and run it up to about 3000 rpms and see if you read 800 mv or so with it wide open. That should at least tell you if the O2 is responding within range as the ECU should go open loop at WOT. If you see something different then the sensor is likely faulty.

You have it. The open loop while cold just show that the sensors are there, then you can watch as they start reporting, if bank one starts reporting in say 20 seconds but bank two takes a minute that would tell you that it has a problem, but not what the problem is. Then once it warms up watch both sensor one voltages for both banks. The images are still wonky so that would make it harder, but if your tool allows you to capture the results you could create a video for later. However watch both sensors at WOT, if they are close to the same voltages the system is reading them correctly and we need to look for a different problem. BUT if you have ordered the parts, you might change out the sensor, just to see how it reports. Also you might want to clear the systems learned values, some scan tools will let you do that in the special tests. That resets things like base idle, fuel trims go to zero and timing resets. Then you start there and see what it does. If you warm it up and still have the system adding fuel then it's time to clamp off all vacuum lines, I have seen bad brake boosters and other vacuum items leak, generally they cause a problem on both banks though. Same with fuel pressure, both sides are fed the same so it likely isn't a bad pump. Ignition is the same, plus an engine misfire would be noticed. Being this is on only one bank it is something else.

We'll be here and hopefully fully operational when you have the data.

OH if you want some fun on a similar situation my friend Paul just did an interesting case showing the testing I'm suggesting, looking at the trims and then a flow test. So you might find them interesting as well.

Yep, it looks like you have an injector that is leaking or you have a catalytic converter that is partially clogged, I would remove the spark plugs on bank two and look at them, you are looking for the one, (or all) that are dark in color. This will be the cylinder that is leaking, also you could have low compression on that cylinder as well. Here is a guide to help check the converter on bank 2

Please go over this guide and get back to us and let us know what you find.

Yes, bank 2 is on the left side of the engine, closest to the front of the car. Let me know what you find.
