Hello, I'd be happy to help! First, there's actually a TSB relating to P0133, stating the the PCM needs to be reprogrammed. P0325 is related to the knock sensor and it's circuit, have you done anything related to that code yet? Do you have access to a scan tool that shows data and not just codes? I'd like to know what the fuel trims are showing as well.
Ok bank 1 seems to be running rich, which is possibly due to that pcm update, what kind of o2 sensors did you replace them with? Exhaust leaks are very common on these and cause the p2096. Now, I'm sure you've tried checking but what process did you use to check for exhaust leaks? Even a very small one will throw this code because it's rediculously sensitive.
Ok, I would take care of that rich condition first, it's possible it's leaning the mixture out when it shouldn't be causing the downstream o2 sensor to see an overly lean condition.
Because it has that TSB I would definitely have them see if it has the updated software first. Like I said, it's adjusting lean because it thinks it's running rich when it may not be because of faulty ecm software.
Ok sounds good.
Ok then you'll need to start by determining what's causing it to run rich. You could have a leaking fuel injector on that side, fuel pressure could be wrong, or you could have a bad new o2 sensor.
The scan tool wouldn't show you if the injectors are leaking or stuck open, that's what you need to look for. Relieve the fuel pressure, hook the pressure guage up and command the pump on with the scan tool then back off and let it sit for a little while and see how much fuel pressure drops with it just sitting
