Importance Of A Scion TC Fuel Injector Cleaning

Over time, your fuel injectors may collect dirt, grime, and soot because of use and external elements. Then, this can result in an imbalance to the air-fuel mixture that can lead to further issues such as rough idling, poor performance, and fluctuating gas mileage. This is why we highly recommend paying close attention to symptoms linked with fuel injector issues and getting them cleaned to avoid problems. Plus, you cannot expect your engine to perform well when your fuel injector is clogged.

First, you need to identify if your fuel injector is dirty. You can do this through regular maintenance. Check for some symptoms linked with dirt in your fuel injector that impact its performance such as the following:

1. Stalling engine and rough idle

Do you notice that your car has a tendency to shake and sputter, particularly when you are stopped? An engine that is idling can be linked with inconsistencies to the RPM. When there is a sudden drop in the fuel supply, which is common when you drive uphill, it may result in rough idling. You may even need to restart your vehicle because the fuel supply is not enough. If this is something that you experience with your car, it means that you will have to clean your fuel injectors.

2. Engine misfiring

Another sign that your fuel injectors are dirty is when the engine misfires. This is identified by a sputtering and inconsistency during acceleration. In fact, acceleration may be poor even if you step on the gas. If this is something you experience frequently, it may be time to clean your fuel injectors because of an imbalance in your air and fuel mixture that enters the engine.

3. Poor fuel efficiency

Dirty fuel injectors may be prone to a reduction in fuel efficiency. Therefore, you may find yourself having a constant need to refill your fuel. It happens because the air and fuel mixture is inefficient. Other engine issues can be linked with this problem, but it is usually a case of having a clogged fuel injector that needs to be addressed right away.

4. Fluctuations with your RPM needle

When everything is going right with your vehicle, the RPM should be working as it should. But when you have dirt in your fuel injector, there is unpredictability in the RPM needle’s movement found on your tachometer. So, it tends to fluctuate a lot.

5. Illuminated check engine light

Whenever your check engine light turns on, it always means that something is not right with your car. There are problems that you may not see right away, which needs to be addressed. If the other symptoms are present and your check engine light turns on, then it may be time to have your fuel injector inspected and cleaned.

Scion TC Fuel Injector Cleaning Facts

Cleaning your fuel injectors is important to ensure their optimal performance. Now, deposit buildups tend to accumulate such as ethanol, which is a fuel source obtained from corn, a plant material. This component in the fuel helps in minimizing carbon monoxide emissions  and is used to boost octane. But it can also be a filler found in cheaper gas. Since it is corrosive as it is alcohol, it can be hard on various vehicle components. Carbon deposit can get dislodged and get into other components of your engine.

Furthermore, the material oxidizes and then emulsifies to create by products that cause a clog in your fuel injectors, to name a few. So, this increases the likelihood of poor fuel economy and inefficient engine performance.

Carbon is another culprit for harmful engine deposit clogs. Since the engine is not capable of extracting all of the energy obtained from fuel, some of it that cannot be combusted becomes deposited in your fuel injectors and exhaust system. It may not be completely avoidable, yet you can reduce the damage to your engine by cleaning parts exposed to this build up such as your fuel injectors. Once you notice problems, it is best to take action sooner than later.

Considering the importance of keeping your fuel injectors clean, you may wonder what the best fuel system cleaner is. Basically fuel system cleaners are useful when they are specifically designed for your vehicle, especially when it runs on gas that contains ethanol.

There are many products in the market that are useful for cleaning your fuel injectors. These may contain potent detergents that give your fuel injectors a good clean up, in addition to other components such as your combustion chambers, carburetor, and intake valves. These cleaning agents help to dissolve carbon deposits and fuel residue, so that it can restore any lost power and minimize occasions of rough idling and hesitation. 

However, it is best to read the ingredients included in the product carefully. The last thing you want is to cause more harm than good to your vehicle by incorporating harsh chemicals to critical parts such as your fuel injectors.
