How to clean fuel injectors effectively on Chevrolet Colorado?

Proper tools required for Fuel Injector cleanup consist of fuel line shut-off adapters (J 37287), Fuel Injector cleaner (J 35800-A), 3/8 fuel line shut-off valve (J 42873-1), 5/16 return pipe shut-off valve (J 42873-2), 3/8 fuel pipe shut-off valve (J 42964-1) and 5/16 fuel pipe shut-off valve (J 42964-2). Before adding top-engine cleaner gm p/n 12346535 in the us or gm p/n 992872 in canada dealers must close the canister valve. The combination for cleaning requires 3.24 oz of top-engine cleaner poured into 29.16 oz of regular unleaded gasoline when different brand solutions are used. To initiate the procedure disconnect the fuel return lines and fuel feed lines before plugging them properly while disabling the vehicle Fuel Pump. Attach the cleaning tank to the Fuel Rail before adding pressure to 510 kpa (75 psi) and let the engine run until it stops. Reconnect the fuel lines to the vehicle then operate it for 2 minutes before ending the process. You should conduct the injector balance test by measuring the fuel pressure reduction of each injector followed by an injector exchange in case the lowest pressure drop is detected. For preventive measures share the port Fuel Injector cleaner gm p/n 12345104 (Canadian P/N 10953467) and explain its dosage of one ounce per gallon of fuel and recommend frequent use of the cleaner to avoid future complications during fuel tank refills. Testing the vehicle on the road will verify if the repair successfully dealt with the concern.
