Facing problems on your automobile is specially frustrating, furthermore the financial burden that these concerns signify, one must also add the time lost with a non-functional Mercury Mariner and the time spent to diagnose and remedy the malfunction. Nevertheless, some problems are less major than others, which is not to say that they do not worry us. On this page we are going to look at a problem that can occur to all of us, having vibrations at acceleration on Mercury Mariner. This problem can oftentimes be tricky to perceive but it must be dealt with. We will consequently commence our article content with the origins of these vibrations on Mercury Mariner, then, with the solutions you have to reduce or stop these tremors.

Why does my Mercury Mariner produce vibrations when accelerating?

So let’s commence our article content with the origins of this kind of problem on your car. You should already know that an engine, specifically if it is old 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 trigger this kind of discomfort, both at idle and when accelerating.

I feel vibrations on my Mercury Mariner only when accelerating

Let’s take the most interesting circumstance for us in this article content. The fact that you suffer trembling on your Mercury Mariner during your acceleration phases, in this situation you will have to examine the condition of some elements because several of elements can be at the source 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 concerned.

  • Turbo: If the turbo of your Mercury Mariner is defective, it may trigger 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 affect the performance of your turbo and create vibrations that you may come to feel at the time of acceleration of your Mercury Mariner.

    • .

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

I’m having vibrations on my Mercury Mariner at acceleration and deceleration

We will now focus on the situation where you come to feel vibrations on your Mercury Mariner when you are accelerating but also when you are idling. If you only come to feel vibrations when you are idling on your Mercury Mariner, please read our article content dedicated to this problem to resolve your problem. If, on the other hand, you notice that your Mercury Mariner vibrates when accelerating but also when it is stopped, here is the list of components to check:

  • EGR valve: In fact this valve which manages the return of exhaust gases for pollution standards can become dirty and disturb the evacuation of exhaust gases which can trigger Mercury Mariner vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control 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 clogged it will not let the fuel pass effectively and therefore disturb the operation of your Mercury Mariner, up to the point of causing vibrations during acceleration.

Here are the main motives of a Mercury Mariner that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Mercury Mariner? What can I do?

Finally, in this last section, we will provide you the solutions available to you to cure these tremors on your car when you accelerate. Here is the best attitude to adopt according to the component that is involved:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Mercury Mariner, it will be good for you to control all the components linked to it because changing a complete turbo is a big budget and most of the time the problem 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 Mercury Mariner to your garage.
  • EGR valve: The EGR valve has the benefit that it is more often than not easy to access and easy 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 Mercury Mariner.
  • Injectors: Injectors are very sensitive components and a few impurities may be enough to disturb 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 only 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 Mercury Mariner. If you don’t feel able to complete certain operations don’t hesitate to go to your auto technician.
