On the other hand, some problems are less serious than others, which is not to say that they do not worry us. In this article we are going to seek out a issue that can affect everyone, perceiving vibrations at acceleration on GMC Sierra. This issue can sometimes be hard to perceive but it must be taken care of. We will so begin our article with the origins of these vibrations on GMC Sierra, then, with the solutions you have to reduce or stop these tremors.

Why does my GMC Sierra emit vibrations when accelerating?

So let’s begin our article with the origins of this sort of issue 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 issue 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 GMC Sierra only when accelerating

Let’s take the most interesting circumstance for us in this article. The fact that you experience trembling on your GMC Sierra during your acceleration periods, in this situation you will have to check the condition of several elements because various of elements can be at the origin of these vibrations and whether or not you are unlucky 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 GMC Sierra is defective, it may bring about vibrations that you will come to 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 bother the behavior of your turbo and create vibrations that you may feel at the time of acceleration of your GMC Sierra.

    • .

  • If the turbo is punctured or harmed, the consequence will be the same, the power supply of your turbo will be troubled and its behavior too. Be sure to visually check their state.

I’m feeling vibrations on my GMC Sierra at acceleration and deceleration

We will now concentrate on the situation where you feel vibrations on your GMC Sierra when you are accelerating but also when you are idling. If you only feel vibrations when you are idling on your GMC Sierra, please have a look at our article dedicated to this issue to get rid of your problem. If, however, you notice that your GMC Sierra vibrates when accelerating but also when it is stopped, here is the list of elements to check:

  • EGR valve: In actual fact this valve which controls the return of exhaust gases for pollution standards can become dirty and disrupt the evacuation of exhaust gases which can bring about GMC Sierra vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that regulating the fuel/air mixture flow may be dirty or damaged, which will release 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 disrupt the performance of your GMC Sierra, up to the point of generating vibrations during acceleration.

Here are the main causes of a GMC Sierra that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my GMC Sierra? What can I do?

Finally, in this last part, we will provide you the possibilities available to you to handle these tremors on your car when you accelerate. Here is the best attitude to adopt according to the part that is affected:

  • Turbo: If your turbo starts all these vibrations when you accelerate your GMC Sierra, it will be good for you to control all the components connected to it because changing a complete turbo is a big budget and typically the issue does not come exclusively 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 GMC Sierra to your garage.
  • EGR valve: The EGR valve has the benefit 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 on cleaning the EGR valve of an GMC Sierra.
  • Injectors: Injectors are very delicate components and a few impurities may be enough to disrupt their performance. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a specialist.
  • Fuel Filter: If it is the fuel filter, just 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 information you need to locate the origin of the vibrations at acceleration on your GMC Sierra. If you don’t feel able to perform certain procedures don’t hesitate to go to your mechanic.
