Exclamation 350z shaking idle and no power like its in Limp mode fix?

I bought a 350z that I'm trying to fix up and I got it running but after a couple pulls it started running so bad I could barley get it back home, I though it was in limp mode but even after clearing the codes it idles really rough and wont rev past 3k while sounding like its popping so much. I had live graph of ECM up while it was driving and idk why the injector b1 is twice the number of injector b2 when it says bank 1 is running lean code. Idk where to start any advice would be helpful, any engine tuners in the chat that could point me in the right direction so I don't spend a year guessing what to change.

Codes are:
P1564, ASCD SW
P1211. TCS C/U Function
P0171, Fuel SYS-LEAN-B1
