Hello I have a 1999 Ford Ranger 6v 3.0L Flex Fuel and my check engine light is on codes p0171 and p0174 (lean bank #2) I changed maf sensor, checked vacuum leaks, put new air filter, new fuel filter, new hoses, added a SeaFoam and I still have the problem! I checked fuel pressure and its 35 psi. Some people say to change fuel injector damper and some say fuel pump! (Fuel pressure regulator comes with fuel assembly). Don't know what to do need help from a pro
