Knowing more about your engine configuration would be helpful. For a Ford vehicle with P0174 (lean mixture), the first step is typically to inspect PCV (Positive Crankcase Ventilation) hoses and elbows. Vacuum leaks, especially around bank #2, are a common cause and should be checked thoroughly.

Ford P0174 is a broad diagnostic code with numerous potential causes. This means the solution could involve various components or repairs—such as faulty oxygen sensors, fuel injectors, intake manifold leaks, or even issues with the mass airflow sensor. A full diagnosis is recommended before replacing any parts.
