Any simple way to determine flex fuel or not? I need injectors for an 03 3.0 2wd, 8th digit of the vin is V but when I go to order the injectors it simple ask if its flee fuel or not. Any help is appreciated

 

V= Flex

 

Yes +1 ^^^^

Flex fuel engines used larger injectors because ethanol has a lower air:fuel ratio(9:1) so more ethanol needs to be added to the engine that gasoline(14.7:1) for same air flow
The Flex Fuel computers are set for these larger injectors so would set Rich codes if you used Gas only injector size

 

Definitely gonna order the correct flex fuel ones, no cost difference between the two, thanks for the guys
