As an expert in automotive maintenance, I can certainly provide you with a detailed guide on how to clean your fuel injectors. It's an essential part of keeping your vehicle running smoothly and efficiently. Here's a comprehensive step-by-step process:

Step 1: Safety First
Before you start, ensure that your vehicle is parked on a level surface and the engine is turned off. Disconnect the negative battery terminal to avoid any electrical mishaps.

Step 2: Locate the Fuel Injectors
Fuel injectors are typically found on the intake manifold of your engine. They are connected to the fuel lines and the electrical connectors.

Step 3: Disconnect the Fuel Lines
Using a fuel line disconnect tool, carefully disconnect the fuel lines from the fuel injectors. Be cautious as there may be some residual fuel that could spill out.

Step 4: Prepare the Cleaning Kit
Get your fuel injector cleaning kit ready. These kits usually include a cleaning solution, a method to connect to the injectors, and sometimes a flow tester to check the injectors' performance before and after cleaning.

Step 5: Apply the Cleaning Solution
Connect the cleaning kit to the disconnected fuel lines. Follow the instructions provided with the kit to apply the cleaning solution into the injectors.

Step 6: Circulate the Cleaning Solution
Some cleaning kits come with a mechanism to circulate the cleaning solution through the injectors. This helps to flush out the built-up deposits.

Step 7: Check the Injectors
After the cleaning process, it's a good idea to use a flow tester to check the performance of the injectors. This will tell you if the cleaning was successful and if there are any injectors that might need to be replaced.

Step 8: Reconnect the Fuel Lines
Once you're satisfied with the cleaning, reconnect the fuel lines to the injectors. Make sure the connections are secure to prevent any leaks.

Step 9: Reconnect the Battery
Reconnect the negative battery terminal and start the engine. Let it idle for a few minutes to circulate the new, clean fuel through the system.

**Step 10: Dispose of the Used Cleaning Solution Properly**
Remember to dispose of the used cleaning solution according to your local environmental regulations.

Important Considerations:
- Not all fuel injectors are designed to be cleaned. Some may need to be replaced if they are clogged.
- Using non-approved cleaning fluids can damage your fuel system components, so always use products recommended for your vehicle.
- If you're not comfortable doing this yourself, it's best to have a professional mechanic perform the service.

By following these steps, you can maintain the health of your fuel injectors and improve the performance of your vehicle. It's a cost-effective way to enhance your car's fuel efficiency and engine performance.
