  • Try to choose a cleaning fluid consisting of polyether amine (PEA), which will diffuse the carbon deposits more adequately than other constituents.
  • You can get this kit for under $100. Also, read the instruction or ask the store owner how to use the fuel cleaning kits.

Different vehicles have different designs, so finding a fuel injector is challenging. Look closely at your vehicle manual to learn where the fuel injectors are placed. Although the fuel injectors are usually under the car’s hood. Still, if you’re unsure, check out the information available online.

7.      Turn on the vehicle

Get your car started, and let it function for about 5 to 10 minutes. So, make sure your fuel pump is turned off. The motor will stop working once the cleaning solutions are flowed through the fluid rail and cycled through the injectors.

8.      Remove the Cleaning kit & Attach your Pump & Injectors Again

Later, you must remove the hose and fitments from your fuel port. And reconnect the fuel pump power cable and the pressure regulator vacuum hose. Place the fuel cap back in its position.

9.      Turn on the Vehicle Again to Know the Fuel Injector’s Working.

After reattaching all the equipment, start the engine to test your vehicle. Keep driving shortly to make sure the vehicle is running steadily. Listen carefully, and if you hear unusual noises from your car, that indicates a problem.
