Although the D13 is noted for its fuel efficiency, while at the same time offering plenty of power, it can have issues at one point or another. 

Furthermore, there were upgrades that were done to it over the years, which makes it a reliable engine that lasts a long time. In fact, it has a rating of B50, which means the mileage can go as much as 1.2 million miles and should go without any problem until an overhaul may be needed.

Thus, it is most definitely a dependable unit with a good amount of power and performance to offer.

Volvo D13 Bad Injector Symptoms

First, let us talk about the D13 injector so you can have a better understanding of how it works and what issues it may come with.

The fuel injector is a key part of your engine, which enables fuel delivery to your combustion chamber. When your fuel injector is working well, it delivers ample fuel to provide notable combustion and good power output. This also helps to minimize emissions as fuel is prevented from inefficiently burning or being wasted.

The injector also helps to make sure that your engine runs efficiently and cleanly. This also helps to minimize vibration and noise. Unfortunately, some issues may come along with your injector. This is why you should pay close attention to some of the common symptoms that come with it such as the following:

1. Stalling

When you have an engine that frequently struggles in providing optimal power on a regular basis, you may experience sudden or gradual power losses when you drive. This also means that your engine turns off immediately, which is dangerous and can lead to accidents.

2. Rough idling

In addition to some stalling issues, you may notice that your vehicle seems rather shaky when you are in idle. It starts off as rough idling then losing power completely. The RPM reading may also appear to be lower than normal, which is unlike what you usually experience in your vehicle. 

3. Reduced Fuel Efficiency

As we have mentioned earlier, the Volvo D13 is generally a fuel efficient engine. However, if you have been noticing the need to top up the fuel more often than usual or if your old engine is using up more fuel, then the fuel economy definitely decreases. But in addition to these things, the fuel consumption is significantly higher than what it used to be, which can be caused by a bad injector.

4. Check Engine Light

We also would like to add that the check engine light tells you a thing or two about the condition of your injector. While it often turns on when you have an engine problem, there are also cases when the check engine light switches on when you have a bad injector. So, if this is the issue, it is best to get your vehicle checked to prevent this problem from getting worse.

5. Increases Engine Noise and Vibration

When your vehicle is running smoothly, it means that everything about it is going well – including the fuel injector. But once too much shaking is happening, or there is too much noise being produced by your engine, then it may be time to get your vehicle checked. You may also notice that the problem results in frequent or loud grinding, whirring, and knocking, which can be very concerning. 

6. Fuel Leaks

Do you observe fuel leaks or streaks of fluid in the engine bay? You can see this in the location of your injector. But it is even worse when you notice fuel droplets on the ground where you have parked your vehicle, particularly the direction perpendicular to the engine bay.

Aside from the leak, a strong fuel smell is another possible sign of a bad injector. The strong odor emitted by the fuel, which is often pungent, is also linked with a bad injector.

What You Can Do 

When you observe these symptoms of a bad injector, this leaves you wondering what you can actually do about it. 

The best thing to do is to get it checked well and perform soem troubleshooting techniques. If the issue is with poor fuel quality, then you may want to refill the tank when there is a need to top it up. If there is contamination to the old fuel, change the fuel filter.

You may also notice a clog to the fuel injector, which results in poor fuel economy and reduced performance. The quickes and cheapest way to address this issue is by cleaning and unclogging the spray tip of your fuel injector. Some common supplies needed are a can of compressed air, gloves, and a cleaning fluid. You may check your manual when you are unsure about how to take the fuel injectors out. Then, you can blow out debris or dirt using the compressed air. 

Clean the fuel injectors with the cleaning fluid and soak them overnight to loosen stubborn buildups that cause the clog. Then, you can reconnect your injectors and start the engine, which should now improve the performance of your vehicle. 

If the issue is withe a worn or defective injector, you will not be able to repair it unless the problem is with the o-ring that needs a replacement. You can also check the injector’s condition in the engine’s individual cylinder. When there is damage or a crack, you will have to replace it. 

Be sure to bleed your fuel system, which helps to prevent air pockets from forming. This also reduces the chances of the engine stalling or rough idling.
