How to Clean Fuel Injectors?

[McLukas]

First, find a suitable screw, screw it in tightly, then pull it out while gently wiggling it left and right. If the screw feels loose, continue tightening it. Use a cloth and paper towels to thoroughly wipe the surface first to prevent large debris from falling inside. Then, use paper towels to clean the interior. Finally, use carburetor cleaner to clean the inside. Even if the fuel injector is slightly clogged, impurities can be flushed away and dissolved during high-gear acceleration. Disconnect the car's fuel pump power supply. For some models, you can remove the fuel pump relay to avoid gasoline spraying from the connections during the cleaning process.
