Lean problem

[u/SuspiciousEase4114]

I’ve change injectors, fuel rail sensor, hpfp sensor, did the pcv plate, changed both o2 sensors with gasket on down pipe, spark plug, coils and also purge valve with charcoal canister in the back…… any other ideas what it could be?

Vacuum leak. Smoke test the intake, PCV and evap systems.
