The key question to resolve is if it is really lean or just thinks it is lean. To determine that you need more data. Once that is known, you can figure out why.
That said, given everything you have already changed and the fact it is throwing both codes leads me to believe it is something common to both banks - since you have already changed the MAF, I am guessing it is bad ECT sensor.

Hi extinct. Thanks for your response I haven’t done this yet as I’m not sure about the hook up to an iPhone. I have a maxi-diag elite diognostics computer and I think that will work. But... I have no idea how to use it 🤣 just pull codes really. My mechanical skill set is a bit more old school than that (I’m used to series LR’s and Ladas 😁
I’ll try and hook it up tonight and report back what I find.
Time for some YouTube tutorials.

Did you do this? You are throwing parts at it with no information. Those codes are typically thrown when the ECU can tell the short and long term fuel trims are excessive - meaning the computer has had to increase the fuel shot outside normal parameters for the MAF reading. The question is if it is still able to compensate and the 02's are cycling or if you outside the boundaries of the fuel tables. If you are outside the boundaries you have a big leak/problem. The elm will also allow us to see the fuel trim, MAF readings, and ECT, so we get an idea of the amount you are off. The fuel map is determined by ECT and MAF - if either are reading different from actual you will have a problem

whst is the. Ect sensor
