Injectors were introduced as a replacement for the old carburettor system, since they help engines run with greater fuel efficiency and also help to reduce emissions.
A car generally has one fuel injector per cylinder. So, if you drive a four-cylinder car, it will most likely have four fuel injectors. Fuel injectors control the volume of fuel delivered to the combustion chamber, ensuring the right amount is injected at the right time.
The process is:. Sometimes fuel injectors can develop faults which impact on their performance or cause breakdowns. This is often due to them becoming clogged with debris, although some mechanical and electrical issues can also affect fuel injectors.
Here, we take a look at some of the common signs and symptoms associated with a faulty fuel injector. The most common sign of a bad fuel injector is the check engine warning light, which appears on the dashboard.
Although there are a few different reasons why a check engine light can switch on, it could be down to a fuel injector. The ECU triggers the warning light when the injector is delivering too much or too little fuel. Does your car often misfire? The fuel injector uses a special nozzle to spray the fuel as mist, instead of a strong jet stream.
Just think of the nozzle on the hose you use in your yard. You can change how the water flows out of your nozzle. There can be jet stream, shower, mist, and many more settings. Fuel injectors can become dirty and clogged over time, which will lead to poor performance, bad gas mileage, and even dirty exhaust emissions. A fuel injector can become clogged around its valve and nozzle.
Build-up can consist of wax, dirt, and other carbon deposits. Most build-up occurs from short trips, meaning a vehicle that normally travels for only fifteen minutes; low-quality gasoline that does not contain detergents also causes build-ups. Detergents can actually clean a fuel injector while you are driving, but many refineries are removing the detergents from their fuel to sell gas at a cheaper price.
If there is a problem with your ECU, it may not be able to tell the fuel injectors how to property mix and deliver the air and fuel to the combustion chambers. Therefore, you may get bad performance even if the fuel injectors are fully intact. If one or more of your fuel injectors are cracked or broken, there is nothing to do but swap in a new one. They may be clogged with dirt and debris. A simple solution is to add fuel injector cleaner, such as our famous Rislone Fuel Injector Cleaner.
This product removes all the gunk and debris from your fuel injector and lubricates your cylinders to help maximize performance.

Signs of Fuel Injector Issues Are you dealing with a problem related to your fuel injectors?
Here are some signs to watch out for: Loss of engine power — If you find yourself getting much less power out of your engine than you should from time to time, a bad fuel injector could be the culprit. It either has a severe case of the Mondays or, more likely, some dirty fuel injectors.
Spotting the signs of dirty fuel injectors and investing in a quick cleaning can help you smooth out your rough ride and get back to care-free cruising. This might be the first time you've heard of fuel injectors, and that's okay. Your car's fuel filter, pump, and injectors are all part of an interconnected though unseen under-the-hood system.
Together, the filter, pump, and injectors ensure your engine receives the correct mixture of fuel and air. Knowing the complicated dance that goes on in your fuel injection system, it's easy to see how bad or dirty fuel injectors can throw a wrench in your engine!
Dirty fuel injectors may cause your vehicle's engine to misfire. This problem makes the motor feel as though it is sputtering — sending vibrations through the car. Such misfires can happen when a fuel injector problem mixes up the delicate balance between fuel and air entering the engine.
Does your vehicle sputter and shake when you're at a stop sign or sitting in traffic? It's not channeling a bucking bronco. It's telling you that there may be dirty fuel injectors at work. Typically, "rough idling" is characterized by varying revolutions per minute RPMs , even when you have your foot off the pedal.
Often, rough idling is accompanied by engine stalling — a sudden decrease in RPMs and engine noise that feels like running out of gas on a hill. Dirty fuel injectors are only one of several engine problems that can result in rough idling and engine stalling.
