I have 97 3400 LIM/UIM/ with rail, injectors, FPR... before I strap the stuff on the 3100 should I just change back to my 3100 injectors and FPR. it should be noted that the 97 3400 injectors are about the same as the 99/3100 injectors... im just not sure about the FPR, if I should use the one I already had... need answer fast!!!

But it might be wise to re-use your injectors if the other ones have been sitting for a while. They might be clogged/sticking. If they dry out they don't do so well.sigpic
