However, some problems are less severe than others, which is not to say that they do not stress us. Today we are going to look at a trouble that can occur to everyone, perceiving vibrations at acceleration on Alfa Romeo Giulietta. This trouble can in some cases be difficult to perceive but it must be handled. We will so commence our article with the origins of these vibrations on Alfa Romeo Giulietta, then, with the answers you have to reduce or stop these tremors.

Why does my Alfa Romeo Giulietta make vibrations when accelerating?

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

I feel vibrations on my Alfa Romeo Giulietta only when accelerating

Let’s take the most interesting circumstance for us in this article. The simple fact that you feel trembling on your Alfa Romeo Giulietta during your acceleration periods, in this scenario you will have to check the condition of some components because several of elements can be at the beginning of these vibrations and regardless if you are unlucky 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 Alfa Romeo Giulietta is faulty, it may generate vibrations that you will come to feel when you accelerate at the moment it is activated.
  • 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 create vibrations that you may come to feel at the time of acceleration of your Alfa Romeo Giulietta.

    • .

  • If the turbo is punctured or injured, the consequence will be alike, the power supply of your turbo will be disturbed and its behavior too. Make sure visually check their state.

I’m getting vibrations on my Alfa Romeo Giulietta at acceleration and deceleration

We will now concentrate on the situation where you come to feel vibrations on your Alfa Romeo Giulietta when you are accelerating but also when you are idling. If you only come to feel vibrations when you are idling on your Alfa Romeo Giulietta, please read our article focused upon this trouble to resolve your problem. If, alternatively, you identify that your Alfa Romeo Giulietta vibrates when accelerating but also when it is stopped, here is the list of components to check:

  • EGR valve: Indeed this valve which manages the return of exhaust gases for pollution standards can become dirty and disturb the evacuation of exhaust gases which can generate Alfa Romeo Giulietta 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 correctly, 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 disturb the performance of your Alfa Romeo Giulietta, up to the point of generating vibrations during acceleration.

Here are the most important causes of a Alfa Romeo Giulietta that vibrates at acceleration

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

Finally, in this last section, we will tell you the possibilities available to you to get over these tremors on your car when you accelerate. Here is the best attitude to adopt dependent on the component that is concerned:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Alfa Romeo Giulietta, it will be good for you to control all the auto parts attached to it because changing a complete turbo is a big budget and most of the time the trouble does not come specifically from the turbo. So make sure you take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Alfa Romeo Giulietta to your garage area.
  • EGR valve: The EGR valve has the benefit that it is generally easy to access and simple to disassemble/clean. You can always examine it and clean it, for this see our article on cleaning the EGR valve of an Alfa Romeo Giulietta.
  • Injectors: Injectors are very fragile auto parts and a few impurities may be enough to disturb their performance. 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, simply replace 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 uncover the origin of the vibrations at acceleration on your Alfa Romeo Giulietta. If you don’t feel able to do certain operations don’t hesitate to go to your technician.
