Update on this truck, my 94 and my new to me 92 extended cab.
The efi is learning more everyday, finally got an air cleaner on it. However I can't say mileage is any better but drive ablility is.
My white 94 I sold for $300 to my younger brother who wants a truck for winter but also so he didn't put as many miles on his sports car either, plus to learn to drive a manual.
I just bought this 92 2wd extended cab 3.0 5speed ranger for $450. The original owner only parked it because he got a new vehicle but couldn't find where the slow coolant leak was. Also doesn't have rear working tail lights only when the headlights are on but the turn signal and brake ones do so that a simple fix. The coolant loss was from the water pump weep hole, easy fix and found it when I got home afted getting it. Also going to need an exhaust and cab corners plus the blend door is having an issue so no heat in the cab atm. I will get the a/c working.
