Default p0171

1995 4.0 4x4. i am getting a po171 code for lean on bank one. i have changed 02 sensors on both sides fuel filter and pump and had a shop check for vacuum leaks and found none. i have also tested the dpfe sensor to make sure it was functioning properly. also have cleaner the maf and have had the injectors out and cleaned and tested them all. i have no idea what else could be causing this issue. has to be something stupid. any help would be appreciated
