What are the consequences of a faulty injector?

Your car's injectors are responsible for atomizing fuel inside the combustion chambers of your engine. The injection system required for good combustion in the cylinders can be direct or indirect, depending on the model. In this article, we will answer all your questions about injector wear: how to recognize it, the consequences of driving with an HS injector and the need to use an injector cleaner!

🔎 How to recognize a faulty injector?

If one or more of the injectors in your car stop working properly, unusual symptoms will appear. Thus, they can take the following forms:

• Fuel leak under your car : If the injector is leaking, fuel will flow out from under the vehicle and form a puddle. This sealing problem often arises from wear on the nozzle seal;
• The engine is losing power : the engine can no longer have the same power as usual due to combustion problems;
• Increased fuel consumption : if the fuel leaks or is injected too much, there will be an overconsumption of fuel;
• Exhaust emits black smoke : incomplete or improper combustion causes thick smoke in the exhaust pipe;
• Difficulty starting a car : you will need to insert the key into the ignition several times before the car can start. If the injectors are severely damaged, the car will not start at all;
• Engine misfires are present during acceleration : there is a risk of jerks or holes during acceleration due to sub-optimal combustion;
• The cabin smells like fuel : Since some of the fuel does not burn and stagnates in the engine, this type of smell is felt in the vehicle interior.

In certain situations, the injector is functional, but it is necessary to replace its gasket. In order to diagnose the exact cause of the malfunction, it will be necessary to call a mechanic.

🚗 Can I ride with the HS injector?

We strongly advise against using the HS injector in your vehicle. After all, a malfunction of this part will have significant influence on the quality of engine combustion and fuel consumption. In addition to increasing gasoline or diesel consumption, it can damage your engine and various parts related to the latter.

Thus, stagnation of unburned fuel can contribute to the creation of calamine and will come and stop certain elements. In the long run, if you continue to drive with the HS injector, you run the risk of engine breakdown. This should not be taken lightly, as replacing an engine is extremely expensive operation compared to simply replacing the injector.

Typically, injector life is between 150 and 000 kilometers depending on the service provided.

⚠️ Can I drive with 4 HS injectors?

In the most serious cases, 4 engine injectors are completely out of order. If you find yourself in such a situation, you are unlikely to be able to start your car. In fact, the engine will receive a tiny amount of fuel or no fuel at all.

If you do manage to start your car, your gas or diesel consumption will skyrocket because most of the fluid will stagnate in the engine before reaching combustion chambers.

You will need to intervene in your car as quickly as possible by bringing it to a professional auto repair shop.

💧 Do I need to use a nozzle cleaner?

Nozzle cleaner is the ideal solution for just maintain your injectors and provide them with greater durability... Thanks to the composition enriched with active ingredients, it will allow degrease the fuel system, clean the combustion chambers and remove water residues... This product must be added to the fuel door before refueling.

In addition, regular cleaning of the injectors limits the build-up of carbon deposits and ensures stable engine performance over time. This can be done in preventive title all 6 kilometer or medicinal name if any of the nozzles appear to be clogged.

When one of your injectors is malfunctioning, you must respond quickly to save it and limit your garage bill. Start with a deep clean to see if this can fix the detected anomaly. However, if the problem persists, contact your nearest garage to have the HS injector replaced. To find a car with the best value for money near your location, use our online garage comparator!
