Why does my Fiat Grande Punto emit vibrations when accelerating?

So let’s begin our article content with the roots of this kind of problem on your car. You should already know that an engine, specifically if it is ancient or if it has been driven quite a bit, can naturally vibrate without being a problem behind it. Large diesel engines, specifically those with a lot of torque, can cause this form of feeling, both at idle and when accelerating.

I feel vibrations on my Fiat Grande Punto only when accelerating

Let’s take the most interesting circumstance for us in this article content. The simple fact that you come to feel trembling on your Fiat Grande Punto during your acceleration phases, in this scenario you will have to check the condition of several parts because various of elements can be at the origin of these vibrations and regardless if you are unfortunate a combination of several of them may also be possible, here is the list of components that can be involved.

  • Turbo: If the turbo of your Fiat Grande Punto is faulty, it may cause vibrations that you will suffer when you accelerate at the moment it is turned on.
  • The turbo pressure sensor: This sensor will manage the pressure exerted in the turbo of your car, if it fails it may disrupt the performance of your turbo and develop vibrations that you may feel within the acceleration of your Fiat Grande Punto.

    • .

  • If the turbo is punctured or damaged, the end result will be the same, the power supply of your turbo will be disturbed and its performance too. Make sure to visually verify their condition.

I’m feeling vibrations on my Fiat Grande Punto at acceleration and deceleration

We will now focus on the case where you feel vibrations on your Fiat Grande Punto when you are accelerating but also when you are idling. If you only feel vibrations when you are idling on your Fiat Grande Punto, please browse our article content dedicated to this problem to resolve your problem. If, alternatively, you realize that your Fiat Grande Punto vibrates when accelerating but also when it is stopped, here is the list of components to verify:

  • EGR valve: In truth this valve which controls the return of exhaust gases for pollution standards can become dirty and disrupt the evacuation of exhaust gases which can cause Fiat Grande Punto vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control the fuel/air mixture flow may be dirty or damaged, which will discharge the wrong amount of mixture and thus prevent your engine block from working properly, 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 disrupt the operation of your Fiat Grande Punto, up to the point of producing vibrations during acceleration.

Here are the main motives of a Fiat Grande Punto that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Fiat Grande Punto? What can I do?

To finish , in this last part, we will provide you the solutions available to you to get over these tremors on your car when you accelerate. Here is the best attitude to adopt depending on the part that is concerned:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Fiat Grande Punto, it will be good for you to control all the components attached to it because changing a complete turbo is a big budget and in most cases the problem does not come directly from the turbo. So make sure to examine your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Fiat Grande Punto to your workshop.
  • EGR valve: The EGR valve has the advantage that it is quite often easy to access and simple to take apart/clean. You can always look into it and clean it, for this see our article content on cleaning the EGR valve of an Fiat Grande Punto.
  • Injectors: Injectors are very sensitive components and a few harmful particles 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 professional.
  • Fuel Filter: If it is the fuel filter, only change it. A fuel filter doesn’t clean itself, so if it is clogged you will just have to replace it with a new one.

Now you have all the info you need to find the source of the vibrations at acceleration on your Fiat Grande Punto. If you don’t feel able to conduct certain operations don’t hesitate to go to your mechanic.
