I had my injectors tested (Knock Out CYL)and #5 was missing at times and weak. #7 was missing at times and weak, but missing worst than #5. What to do next? Do I pull them and have the bench tested or just replace them? Now that #7 and 5 are on the same plug to the UVCH could that be my problem? Just looking for someones input. Also should it be okay to drive for a few weeks.
