I just finished all the part replacement and cleaning associated with, a HPFP catastrophic failure. I replaced all the injectors. The car runs and drives strong with no drivability issues. Is coding the injectors an absolute must? I don't want to have any problems down the road. I wouldn't mind coding the injectors, but I can't for the life of me find out how to do it with an OBD Eleven. Does anyone know how to code injectors with and OBD Eleven? If not is it really that important?
