It's your fuel pump. The stock Ranger pump does not have enough volume for the 5.0. Pressure yes, but not volume. Under a load it's leaning out and as the RPM's rise the load evens out requiring less volume.
shamus i have a 45lb in line for mustang pump on truck u think the fuel pump is to far away from the tank and on the wrong side of the filter. ray mccoy .
If i remember right the 85 rangers have to filters. On the f-150 (EFI) the pump is in the middle of the two filters.On a stock 5.0 the pressure only needs to be around 39 psi.
