What is engine torque?
The gasoline-powered car engine, known as the internal combustion engine, contains a set of parts connected to each other, which are needed to operate it and move the car, and among these parts are the pistons or “pistons”, they move up and down inside the cylinders due to the explosion process, and the crankshaft converts this energy into a rotational force, which is torque.
Torque is simply a measure of the effort your car's engine exerts while working, and the greater the torque, the more power the engine can produce, so if your car's engine has a lot of torque, it means that your car can accelerate faster, and torque is very important when your car is loaded with things or pulling a trailer and the like.
To visualize torque more and have a clearer picture of it, imagine that you are holding a wrench and want to loosen a nut, when you start applying force to the wrench to loosen the nut, the force you are applying is torque, torque is calculated by multiplying the force your hands exert on the wrench by the length of the wrench, and torque is calculated by multiplying the force your hands exert on the wrench by the length of the wrench.
To simplify, when you use a longer wrench, you get more torque, for example, if you apply 1 kg of force with a 30 cm wrench, you apply 1 kg of torque to the nut, but if you apply the same amount of pressure with a 3 meter wrench, it means that the torque force applied to the nut will be about 9 kg.

What are the symptoms of weak engine torque
There are several symptoms that accompany weak engine torque, and we will present them to you as follows:
Check Engine Light comes on
The function of the check engine light in any car is to appear in the dashboard when an engine issue is detected, and when you see it in front of you, you must check the engine to detect the issue, and engine issues usually affect torque and performance, so when you see the check engine light, you may notice a decrease in the car's torque.
Engine malfunction
There is a very important symptom of weak engine torque, which is the dysfunction of the engine in the first place, as the engine consists of many parts, in addition to several components associated with it that ensure its work and the work of the car, and if one of these parts or components is exposed to a malfunction or malfunction, the whole engine will malfunction and its torque will definitely weaken, especially if the issue is in the fuel and ignition system.
No power in the engine
The work of the car engine depends on the power and energy it produces, which are carefully calculated ratios from car manufacturers, and if any malfunction occurs in the work of the engine, the power and performance will decrease from the normal situation, so much so that you will notice that your car lacks power in certain circumstances.
The engine can only be started after several attempts
Another symptom of low engine torque is the inability to start the engine except after several attempts, if the engine pressure is low in one or more cylinders, your car will only start after maybe 2 to 5 or 6 times and may not start, and this happens because your car's engine does not have enough pressure to ignite the air-fuel mixture.

High fuel consumption
If your car's fuel consumption is normal, it means that the engine is working efficiently and without issues, but if you notice that your car's gasoline consumption is rising and you are spending extra money on it, it means that there is an issue with your car, especially the engine, and this issue not only affects the consumption, but also affects the torque, which will become weaker.
You'll hear sounds you've never heard before
We all know the normal engine sound while working, especially if you have owned your car for a long time, you will know all the sounds that come from it in normal mode and when the engine is trouble-free, but when your engine starts making new and strange sounds, it means that there is an issue that you need to know very quickly to avoid other costly issues.
You smell strange odors
When an unpleasant or strange odor emanates from your car, especially from the exhaust outlet, there is a very high chance that you will smell it or one of your relatives or friends will notice it and tell you about it, and strange odors come from the exhaust when there is something wrong with the engine, so you should know the cause of this odor and do not underestimate it, as it will weaken the engine torque and may cause major issues later on.
Engine still running after shutdown
It is a rare occurrence, but it can happen to you, especially if your car is a modified, high-performance sports car; when the engine is turned off, the octane rating of the fuel may be incorrect, causing it to continue to run even after it is turned off, or the cause may be a faulty electrical coil or incorrect carburetor calibrations.
Engine running rough
Carbon buildup, worn spark plug spark points and other issues can cause the engine to run rough, and this roughness will reduce torque and lead to fuel consumption, or there may be an issue with battery life or fuel quality.
