Encountering problems on your motor vehicle is especially frustrating, furthermore the financial burden that these complications signify, one must also add the time lost with a non-functional Subaru Legacy and the time spent to establish and fix the breakdown. However, some problems are less severe than others, which is not to say that they do not worry us. In this article we are going to seek out a problem that can occur to many of us, perceiving vibrations at acceleration on Subaru Legacy. This problem can often be tricky to perceive but it must be dealt with. We will therefore commence our guideline with the sources of these vibrations on Subaru Legacy, then, with the solutions you have to reduce or stop these tremors.
Why does my Subaru Legacy make vibrations when accelerating?
So let’s commence our guideline with the sources of this type of problem on your car. You should already know that an engine, especially if it is old or if it has been driven quite a lot, can naturally vibrate without being a problem behind it. Large diesel engines, especially those with a lot of torque, can cause this sort of discomfort, both at idle and when accelerating.
I feel vibrations on my Subaru Legacy only when accelerating
Let’s take the most interesting case for us in this guideline. The simple fact that you experience trembling on your Subaru Legacy during your acceleration periods, in this scenario you will have to verify the state of some elements because many of elements can be at the origin of these vibrations and whether or not you are unfortunate a mix of several of them may also be possible, here is the list of auto parts that can be involved.
- Turbo: If the turbo of your Subaru Legacy is faulty, it may cause vibrations that you will come to feel when you accelerate at the moment it is activated.
- The turbo pressure sensor: This sensor will control the pressure exerted in the turbo of your car, if it fails it may bother the behavior of your turbo and develop vibrations that you may come to feel within the acceleration of your Subaru Legacy.
- If the turbo is punctured or harmed, the effect will be similar, the power supply of your turbo will be disturbed and its behavior too. Make sure to visually check their state.

I’m feeling vibrations on my Subaru Legacy at acceleration and deceleration
We will now concentrate on the situation where you come to feel vibrations on your Subaru Legacy when you are accelerating but also when you are idling. If you only come to feel vibrations when you are idling on your Subaru Legacy, please have a look at our guideline focused on this problem to remedy your problem. If, alternatively, you realize that your Subaru Legacy vibrates when accelerating but also when it is stopped, here is the list of things to check:
- EGR valve: Indeed this valve which manages the return of exhaust gases for pollution standards can become dirty and disrupt the evacuation of exhaust gases which can cause Subaru Legacy vibrates when accelerating but also when stopped.
- Injectors: Your injectors that regulating the fuel/air mixture flow may be dirty or damaged, which will generate the wrong amount of mixture and thus prevent your engine block from working effectively, it is even possible that one or more of your cylinders are not running effectively.
- Fuel Filter: Like the injectors, if the filter is blocked it will not let the fuel pass effectively and therefore disrupt the operation of your Subaru Legacy, up to the point of leading to vibrations during acceleration.
Here are the most important motives of a Subaru Legacy that vibrates at acceleration
What can I do to stop the vibration when I accelerate on my Subaru Legacy? What can I do?
Finally, in this last part, we will give you the solutions available to you to overcome these tremors on your car when you accelerate. Here is the best attitude to adopt in accordance with the part that is involved:
- Turbo: If your turbo starts all these vibrations when you accelerate your Subaru Legacy, it will be good for you to control all the auto parts associated with it because changing a complete turbo is a big budget and most of the time the problem does not come directly from the turbo. So be sure to take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Subaru Legacy to your workshop.
- EGR valve: The EGR valve has the benefit that it is more often than not easy to access and simple to disassemble/clean. You can always check out it and clean it, for this see our guideline on cleaning the EGR valve of an Subaru Legacy.
- Injectors: Injectors are very delicate auto parts and a few impurities may be enough to disrupt their operation. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a specialist.
- Fuel Filter: If it is the fuel filter, simply replace it. A fuel filter doesn’t clean itself, so if it is clogged you will basically have to replace it with a new one.
Now you have all the info you need to uncover the origin of the vibrations at acceleration on your Subaru Legacy. If you don’t feel able to conduct certain procedures don’t hesitate to go to your repair shop.
