I have a 99 Ford ranger xlt, 4.0, 4x4, automatic. It throws codes p0174 and I think 0173 but they say its running lean. On a full tank of gas 16.5 it gets bout 160 miles to 180 miles on a tank. Ive switched maf sensor checked intake for leaks and air box all that stuff. Still nothing. Doesnt say anything bout o2 sensors. Ive heard may fuel pressure regulator? What bout vaccum lines on the back of the motor. Looking for help

If the check engine light is on, have the computer scanned. Check fuel pump pressure to make sure it is within spec. As far as the vacuum hoses beind the engine, they run to the 4wd.
