when i drive my ranger, 06 2.3, 2wd , 4.10 gears, bout 64k miles, recent plugs, wires, trans flush, but still, just doesnt seem to have alot of take off power, but yet, at we we have 2 other rangers, that dont get taken care and beat on a regular basis, (not by me). and they seem to have more take off power than mine? are the fleet rangers geared different? there also 2.3 2wd autos, i work for pepboys as a mechanic, and we have them as part delievery trucks just like advance autozone, etc. sorry for the long post i just wondered bout it.
