330Ci P0171, 0174, and 0455 code help

I have a 2001 330Ci with a P0171, 0174, and 0445 code in. It stalls a lot in the first few minutes it's running, and seems to almost be holding back a lot of power sometimes when it runs. I've already checked the gas cap, trying to figure out where to go from here, any advice?

P0171 and p0174, just had those codes bank 1&2 are lean. It was my lower intake boot. Just changed it yesterday and so far it's driving better. Every now and then before I changed the boot, my car would sputter. Now it's not doing that. Usually ppl will tell u it is an o2 sensor. But check the boot FIRST!! Hope that helps!
