An optimally performing fuel injector will ensure maximum power, maximum mileage and maximum economy for your vehicle. Over a period of time, the fuel injector becomes clogged due to carbon and other residues from continually burning gasoline. Unlike the common belief, gasoline is not clean and the additives can easily build up in and around the fuel injector. The high pressure and heat will make the non-combustible particles solidify, blocking the proper jet of fuel from being sprayed by the fuel injector. Many car companies recommend the use of top tier gasoline for their cars because this contains an optimal level of fuel injector cleaners mixed with the gas. However, if you use low priced gasoline for your car, the fuel injector will become clogged sooner, rather than later.
The symptoms caused by fuel injector problems are similar to a broken spark plug or bad coil. You need to be an expert to identify that the problem is actually caused by fuel injectors. Poor idle and starting troubles are classic symptoms of fuel injector problems. Poor engine performance and failed emission test can signal that the fuel injector is not supplying an adequate amount of fuel. Problems with the injector may force the Engine Control Unit (ECU) to read the sensors in the wrong way, resulting in the engine running rich. If that happens, you will experience increased fuel consumption. If left uncared, this can result in catastrophic engine failure.
On the internet, you can find numerous fuel injector cleaning kits and YouTube tutorials on how to use them. If you are a DIY-er, you may be tempted to use one of these kits for your vehicle. Unless you are an expert, you should never assemble or disassemble your engine parts. Driving a car for several decades doesn’t make you an expert on modern engine parts. Nevertheless, if you want to try to clean fuel injectors on your own, you have to be extremely careful.
After purchasing the appropriate fuel injector cleaning kit, disconnect fuel pump from the fuel injector. You should then proceed by disconnecting the vacuum line on the pressure regulator. Follow this up by having the cleaning kit connected to the test port on the fuel pressure line. You should follow the manual in your cleaning kit to accomplish this. Remove the fuel tank cap to prevent build up of excessive pressure. Turn on the vehicle and allow the engine to run. The entire process should complete in about 15 minutes and the engine will turn off automatically at the end of the process. Once the process is complete, remove the cleaning kit. Reattach the pressure regulator and fuel pump supply. Attach the fuel tank cap and start the engine to ensure that it works.
Before attempting fuel injection cleaning on your own, you should remember that this is not a DIY project and there is no guarantee that your fuel injector is clean. The best thing you can do for your car is taking it to professionals for a thorough cleaning and testing of fuel injectors. This will help you to keep your car in perfect running condition, even though professional cleaning service is expensive.
