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
have the same problem?
