Your car is shaking and losing power, you feel it can stall at any moment? This little trouble sometimes happens on a Lexus GS and it is necessary to identify the cause because it can have more serious consequences in the future. In this article, we will try to give you an answer and identify all the potential causes that can make your Lexus GS shake.


Factors that makes your Lexus GS shake


The first thing to do as a diagnosis on your Lexus GS is to clean the various parts. Actually, dirty parts can cause acceleration problems. So check your filters, as air and fuel pass through this path before attaining the injectors. If the road was blocked, think of it as a blocked highway, everything isretarded down. Clean them, and if they are too old, it is reasonable to change them.

Injectors of your Lexus GS:

Directly linked to these filters, the injectors get the fuel through the filters, and then supply the combustion chamber, where the spark plugs ignite the fuel, which allows your Lexus GS to move forward thanks to this process. If you had poor quality fuel or simply fouling at this level, the pressure of the injection pump could be affected, and therefore combustion would no longer be correct. Of course, this will be experienced in the acceleration of your Lexus GS.


As explained above, the spark plugs ignite the fuel once it reaches the combustion chamber. If it hasn’t had any problems so far, most likely that’s where it comes from. If the spark plugs are defective and have difficulties igniting the fuel, you will have trouble driving smoothly with your Lexus GS. Check them and change them if necessary.

Hoses of your Lexus GS:

In your Lexus GS, you have little hoses that are comparable to small pipes that also make possible the transport of different fluids. They need to absolutely remain waterproof, otherwise you will also end up shaking because the fuel or oxygen supply will not be heterogeneous.


Another point to check if the Lexus GS shakes is the calculator. This one is responsible for the ignition but also for the injection. It sends orders electronically to make sure that this task is completed. Imagine a conductor giving inconsistent instructions to the orchestra, it would end into a rather chaotic situation. The same is true for your Lexus GS, which would end up shaking. If the calculator is involved , it becomes more difficult to manage yourself. It is more reasonable to go to a garage to have it recalibrated or replaced if it is not repairable.

Conclusion :

Here are the main motives that could cause your Lexus GS to shake. It is necessary to note that it is often dirty and generally poorly taken care of parts that will cause this. Try to regularly monitor the inside of your Lexus GS by cleaning what you can.
