Why does my Cadillac DTS release vibrations when accelerating?

So let’s begin our content with the sources of this type 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 cause this sort of sensation, both at idle and when accelerating.

I feel vibrations on my Cadillac DTS only when accelerating

Let’s take the most interesting circumstance for us in this content. The simple fact that you suffer trembling on your Cadillac DTS during your acceleration phases, in this scenario you will have to check the state of some elements because various of elements can be at the source 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 parts that can be concerned.

  • Turbo: If the turbo of your Cadillac DTS is faulty, it may cause vibrations that you will suffer when you accelerate at the moment it is turned on.
  • 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 come to feel within the acceleration of your Cadillac DTS.

  • If the turbo is punctured or damaged, the end result will be similar, the power supply of your turbo will be disturbed and its behavior too. Make sure visually verify their condition.

We will now focus on the case where you come to feel vibrations on your Cadillac DTS when you are accelerating but also when you are idling.

If, on the other hand, you notice that your Cadillac DTS vibrates when accelerating but also when it is stopped, here is the list of items to verify:

  • EGR valve: Indeed this valve which controls the return of exhaust gases for pollution standards can become dirty and bother the evacuation of exhaust gases which can cause Cadillac DTS 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 effectively, it is even possible that one or more of your cylinders are not running properly.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass properly and therefore bother the performance of your Cadillac DTS, up to the point of generating vibrations during acceleration.

Finally, in this last section, we will provide 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 part that is involved:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Cadillac DTS, it will be good for you to control all the parts connected to it because changing a complete turbo is a big budget and in most cases the problem does not come precisely 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 Cadillac DTS to your garage area.
  • EGR valve: The EGR valve has the advantage that it is often easy to access and simple to disassemble/clean. You can always check out it and clean it, for this see our content on cleaning the EGR valve of an Cadillac DTS.
  • Injectors: Injectors are very delicate parts and a few impurities 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 professional.
  • Fuel Filter: If it is the fuel filter, just 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 Cadillac DTS. If you don’t feel able to do certain operations don’t hesitate to go to your repair shop.
