Have you get the car tuned since installing the injectors and the fuel pump?

That code is ...running lean on bank 1---
so you got tuned and its too lean...

Cant see how you could add injectors and a pump--which both richen the injection system at all points and come up lean if your not tuned--

enlighten us..
