To identify and replace the injector with the lowest pressure drop the technician must perform the balance test on all injectors. Each gallon of gasoline should receive a one-ounce addition of Port Fuel Injector Cleaner GM P/N 12345104 or Canadian P/N 10953467 into the fuel tank with instructions for the customer to employ GM Port Fuel Injector Cleaner at regular intervals to avoid future issues.
