Sorry for not posting in a while. I replaced all 8 injectors and the fuel filter. Truck runs smooth as silk now. However, i am still getting the 1093 code and when i put a tune in it it seems that it has no more power than stock. I know that it accepts the tune. It smokes just a hair more than stock but i should be smokin tires and it really has no power. Im wondering if it could be the prv? But from what i hear the lb7s really dont have that problem. Can i do the bottle test for an lb7 or does that only work on lly?
