On the other hand, some problems are less severe than others, which is not to say that they do not worry us. On this page we are going to look into a trouble that can occur to all of us, having vibrations at acceleration on Alfa Romeo 159. This trouble can in some cases be hard to perceive but it must be taken care of. We will therefore begin our guideline with the roots of these vibrations on Alfa Romeo 159, then, with the solutions you have to reduce or stop these tremors.

Why does my Alfa Romeo 159 emit vibrations when accelerating?

So let’s begin our guideline with the roots of this type of trouble on your car. You should already know that an engine, specifically if it is ancient or if it has been driven a lot, can naturally vibrate without being a trouble behind it. Large diesel engines, specifically those with a lot of torque, can bring about this sort of discomfort, both at idle and when accelerating.

I feel vibrations on my Alfa Romeo 159 only when accelerating

Let’s take the most interesting case for us in this guideline. The simple fact that you undergo trembling on your Alfa Romeo 159 during your acceleration phases, in this situation you will have to check the condition of several parts because several of elements can be at the beginning of these vibrations and even if you are unfortunate a combination 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 Alfa Romeo 159 is faulty, it may bring about vibrations that you will feel when you accelerate at the moment it is running.
  • The turbo pressure sensor: This sensor will manage the pressure exerted in the turbo of your car, if it fails it may disturb the behavior of your turbo and deliver vibrations that you may feel within the acceleration of your Alfa Romeo 159.

    • .

  • If the turbo is punctured or injured, the result will be alike, the power supply of your turbo will be disturbed and its behavior too. Be sure to visually verify their state.

I’m experiencing vibrations on my Alfa Romeo 159 at acceleration and deceleration

We will now focus on the case where you feel vibrations on your Alfa Romeo 159 when you are accelerating but also when you are idling. If you only feel vibrations when you are idling on your Alfa Romeo 159, please consult our guideline dedicated to this trouble to get rid of your problem. If, however, you realize that your Alfa Romeo 159 vibrates when accelerating but also when it is stopped, here is the list of components to verify:

  • EGR valve: Indeed this valve which controls the return of exhaust gases for pollution standards can become dirty and disturb the evacuation of exhaust gases which can bring about Alfa Romeo 159 vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control the fuel/air mixture flow may be dirty or damaged, which will bring out 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 correctly.
  • Fuel Filter: Like the injectors, if the filter is blocked it will not let the fuel pass correctly and therefore disturb the operation of your Alfa Romeo 159, up to the point of generating vibrations during acceleration.

Here are the main causes of a Alfa Romeo 159 that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Alfa Romeo 159? What can I do?

To conclude, in this last section, we will provide you the solutions available to you to cure these tremors on your car when you accelerate. Here is the best attitude to adopt depending on the component that is concerned:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Alfa Romeo 159, it will be good for you to control all the auto parts connected to it because changing a complete turbo is a big budget and generally the trouble does not come specifically from the turbo. So make sure you examine your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Alfa Romeo 159 to your garage area.
  • EGR valve: The EGR valve has the advantage that it is quite often easy to access and simple to disassemble/clean. You can always look into it and clean it, for this see our guideline on cleaning the EGR valve of an Alfa Romeo 159.
  • Injectors: Injectors are very delicate auto parts and a few harmful particles may be enough to disturb their operation. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a expert.
  • 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 only have to replace it with a new one.

Now you have all the information you need to locate the origin of the vibrations at acceleration on your Alfa Romeo 159. If you don’t feel able to complete certain procedures don’t hesitate to go to your mechanic.
