P1131 and P1152  Lean system Upstream 02 sensor not switching

No vacuum leaks ? These 2 code always appear together  as a lean Bank fuel trim and are mostly  caused by   vacuum leaks, If there is no vacuum leaks  will need to do a fuel pressure test, not only fuel pressure but a volume test of the fuel pump. The fuel pressure has to be 30 - 65 psi
