on a 4.8 and a 6.0. I am running the 4.8 injectors but dont know if there is any difference in the 6.0 injectors. I am getting o2 sensor codexs and wondered if I went ahead and swapped them out if that would help anything before buying o2's

 

nah the 4.8 and 6.0 injectors are the same. I believe(and don't quote me on this) the trucks with lq9's have 30# injectors and the ones with lq4's have 24#'ers. There is a very good possibility all of them have 24#ers though.

 

it depends on year, and if the injectors were on a motor
that was made to run e-85 fuel and gas.
