Re: need better mpg and power
That's either a 3.0L or 4.0L.
3.0L's have a longer stroke and smaller pistons than it's predecessor, the 2.9L. It makes power at higher RPM bands, but they screwed up by giving the 3.0L Rangers an awful rear end gear ratio.
If you took a 2.9L stock off the lot and compared it to the 3.0L, the 2.9L would out do the 3.0L. Had they geared it higher, that wouldn't be true. Though ironically, the 3.0L makes less torque and a little more h.p. (5) The gears are not helping any either. I'm guessing that it's taking a ton of fuel to make enough power to turn those mudders.
For each rotation, the wheel needs to travel a greater circumference. So over all, as far as the transmission is conserned, the amount it would need to turn the rear end is much less to go the same distance, but it's much more difficult, in turn causing the engine to work harder.
Scan the codes as well, there may be other issues contributing to the bad air/fuel mixture!
