P0171,P0174

Hello my name is Brent and thanks for excepting me. I own 3 Yotas. 09 Camry sport with 216,000 miles, 98 4runner limited 2x4 with custom lift on 33s with 336,700 milesand the 05 tacoma 4x4 4.0 access cab with 227,000 miles with 6” RC suspension lift, RC UCAs, custom dual RC steering stabilizer sitting on 33x12.50R17 Nitto Recon grappler a/t with 17x10 ION ALLOY w/ -12 offset and 2” wheel spacers.
05 tacoma keeps throwing codes P0171 and P0174. 3rd gear - 6th gear, it kinda stutters a little bit. The truck cranks right up but has a bit of a rough idle at times. I cleared the codes a couple times just to see and they keep coming back like a crazy woman. Bank 1 too lean bank 2 too lean. I have an OBD2 scanner but not sure how to read some of the live data. Not knowing for sure, I replaced the MAF sensor, all 4 o2 sensors and searched everywhere for vacuum leaks. They have 90 different diagnoses. Any help would be appreciated.
