2001 Ford E-150 Econoline 4.2L MIL Lamp on
When I got this the mil light is on with code po 171 and po 174 Fuel pressure is good so I immediately check for vacuum leaks with a propane sniffer and checked the manifold as well as the pcv connections and found no leaks, Even used carb cleaner but no leaks...
