On the other hand, some problems are less serious than others, which is not to say that they do not stress us. On this page we are going to take a look at a problem that can affect many of us, feeling vibrations at acceleration on saab 9 3. This problem can occasionally be complex to perceive but it must be taken care of. We will therefore commence our article with the roots of these vibrations on saab 9 3, then, with the solutions you have to reduce or stop these tremors.

Why does my saab 9 3 make vibrations when accelerating?

So let’s commence our article 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 lot, can naturally vibrate without being a problem behind it. Large diesel engines, specifically those with a lot of torque, can bring about this sort of impression, both at idle and when accelerating.

I feel vibrations on my saab 9 3 only when accelerating

Let’s take the most interesting case for us in this article. The fact that you suffer trembling on your saab 9 3 during your acceleration phases, in this situation you will have to examine the state of several elements because various of elements can be at the starting point of these vibrations and whether or not you are unlucky a mix of several of them may also be possible, here is the list of components that can be involved.

  • Turbo: If the turbo of your saab 9 3 is defective, it may bring about vibrations that you will 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 disrupt the behavior of your turbo and develop vibrations that you may feel at the time of acceleration of your saab 9 3.

  • If the turbo is punctured or damaged, the end result will be the same, the power supply of your turbo will be troubled and its behavior too. Remember to visually check their state.

I’m having vibrations on my saab 9 3 at acceleration and deceleration

We will now concentrate on the scenario where you feel vibrations on your saab 9 3 when you are accelerating but also when you are idling. If you only feel vibrations when you are idling on your saab 9 3, please have a look at our article focused on this problem to solve your problem. If, however, you realize that your saab 9 3 vibrates when accelerating but also when it is stopped, here is the list of components to check:

  • EGR valve: In truth this valve which controls the return of exhaust gases for pollution standards can become dirty and bother the evacuation of exhaust gases which can bring about saab 9 3 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 performance of your saab 9 3, up to the point of leading to vibrations during acceleration.

Here are the most important triggers of a saab 9 3 that vibrates at acceleration

So make sure take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your saab 9 3 to your mechanic.
  • EGR valve: The EGR valve has the advantage that it is quite often easy to access and simple to disassemble/clean. You can always take a look at it and clean it, for this see our article on cleaning the EGR valve of an saab 9 3.
  • Injectors: Injectors are very delicate components and a few harmful particles may be enough to bother their performance. 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, only 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 find the origin of the vibrations at acceleration on your saab 9 3. If you don’t feel able to complete certain operations don’t hesitate to go to your motor mechanic.
