Why does my Alfa Romeo 156 release vibrations when accelerating?

So let’s begin our article with the roots of this form 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 bit, can naturally vibrate without being a problem behind it. Large diesel engines, especially those with a lot of torque, can provoke this sort of impression, both at idle and when accelerating.

Let’s take the most interesting circumstance for us in this article. The fact that you experience trembling on your Alfa Romeo 156 during your acceleration periods, in this scenario you will have to verify the state of different elements because many of elements can be at the starting point of these vibrations and whether or not 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 Alfa Romeo 156 is defective, it may provoke vibrations that you will suffer 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 affect the behavior of your turbo and bring about vibrations that you may experience at the time of acceleration of your Alfa Romeo 156.

We will now look into the scenario where you experience vibrations on your Alfa Romeo 156 when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your Alfa Romeo 156, please read our article focused on this problem to remedy your problem. If, alternatively, you detect that your Alfa Romeo 156 vibrates when accelerating but also when it is stopped, here is the list of items to verify:

  • EGR valve: In actual fact this valve which manages the return of exhaust gases for pollution standards can become dirty and bother the evacuation of exhaust gases which can provoke Alfa Romeo 156 vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control 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 properly, 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 bother the operation of your Alfa Romeo 156, up to the point of leading to vibrations during acceleration.

So make sure examine your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Alfa Romeo 156 to your workshop.
  • EGR valve: The EGR valve has the advantage that it is often easy to access and simple to disassemble/clean. You can always look into it and clean it, for this see our article on cleaning the EGR valve of an Alfa Romeo 156.
  • Injectors: Injectors are very fragile components and a few harmful particles may be enough to bother 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, simply change it. A fuel filter doesn’t clean itself, so if it is clogged you will simply have to replace it with a new one.

Now you have all the information you need to discover the cause of the vibrations at acceleration on your Alfa Romeo 156. If you don’t feel able to accomplish certain operations don’t hesitate to go to your mechanic.
