Injectors for a 2002 3.0L ranger

[SB0409]

Hey I was just wondering, would it be best to get the 14lbs injectors or I’ve seen people talking about the 19lbs injectors like the F87E-B2A? Would the bigger injectors be any better? The engine is pretty much stock except a cold air filter adapter which shouldn’t really affect this much… any help would be appreciated

Fuel injectors are not the same as Jets in a carb
The computer is pre-programmed for fuel injector size, and fuel pressure PSI, so it can calculate how long each injector should be opened for XX amount of gasoline to flow in

Larger injectors would just cause Rich Codes
Smaller Lean codes
Engine is never running rich or lean, thats not what those codes mean, they mean the computer is having to close injectors sooner(rich) or leave injectors open longer(lean)
So engine always gets correct amount of gasoline, you just now have codes, lol

Go with stock size for 2002 3.0l Ranger
But I thought the were 17lbs after 2001 so same injector size on gas only or Flex fuel, but could be mistaken

Yes but the computer also monitors this and adjusts called fuel trims and they can make up for changes to a point
