Look at the VIN, in windshield corner or drivers door label

8th digit is engine type/size
U = 3.0l gas only
V = 3.0l Flex Fuel

The computer is different and so are the injectors, these must match or you will get lean or rich codes, depending on the mismatch
Flex computer with gas only injectors = Lean codes
Gas only computer with flex injectors = Rich codes

VIN will tell you which computer you have, unless you think its been swapped

I think only the 1999/2000 Rangers had the fuel sensors

Then you have a gas only 3.0l and computer, and no fuel sensor, so you should be using the smaller injector size, flex fuel injectors would cause Rich codes

Injectors are not like Jets on a carburetor, so larger injectors won't give more power, it will just cause Rich codes
