5 Causes of Car Not Accelerating When Pressing Gas
There are lots of different symptoms of a vehicle not accelerating when pressing gas and some of them are very serious and hard to repair. As we all know, a car is a complex machine which is crafted out of lots of parts and components.
So, it is usually not the case that the car won’t accelerate because of only one thing. The car can malfunction easily if only one part is broken or damaged.
Now, let’s see exactly some of the most important symptoms of a car not accelerating when pressing the gas.
5 Causes of Car Not Accelerating
First of all, we need to point out that every car is a bit different. But they basically work the same way. Therefore, most of the cars that are malfunctioning are definitely to be checked by the professional in that field, for the best results.
However, there are 5 most common causes of a car not accelerating when pressing the gas and we are going to discuss them now. Let’s see.
1) Problems With Clutch
First and one of the most common problems of a car not accelerating is usually the clutch. Now, the clutch plays a massive roll in the car acceleration since it engages the transmission with the engine.
So, how exactly does the clutch affect the acceleration? Well, if you can’t shift into another gear properly, your car won’t accelerate at all.
That is like being stuck in the one gear and pressing a gas pedal so hard, but, your car simply refuses to work with you. Usually, people who have these kind of problems with their cars talk to their local car shops and learn exactly what is going on.
However, there are only two different possibilities here.
- 1If the clutch is not working properly, it definitely is because it is worn out or there is no clutch fluid.
- 2Also, the clutch fluid definitely shouldn’t go above the maximum level, neither should it go under the minimum level as well.
Anyhow, there are some signs that you might want to look at before your car stops acceleration. Simply put, you need to watch out and look how clutch actions go.
If you think that your clutch is to loose or perhaps it doesn’t react to the pressure, your car will have some problems accelerating later.
2) Leaks in hoses
As we all know, there are plenty of different vacuum hoses in the car’s engine, and they are all equally important. Simply speaking, vacuum hoses are mainly responsible for transporting the fuel and the air in the engine. Also, they transport the air out of the engine as well.
You will definitely feel and see the difference in your car’s behavior if there is a vacuum hose leak. One of those problems that are caused by leaked vacuum hoses is the acceleration problem.
So, what exactly happens inside the engine when the hoses leak?
- First, if there are some leaks, your car won’t get the proper amount of fuel that is needed to accelerate.
- Second, the air filter and the air transmission leaks as well, which results in the car malfunctioning and not being able to accelerate at all.
- Simply speaking, you can’t and won’t be able to accelerate at all if your car has leaks in the vacuum hose.
3) ECU Problems
Now, the electronic control unit is quite important for a car’s performance and overall quality as well. But, what happens when the car is experiencing some problems with the ECU.
Simply speaking, the computer can get confused and read some signs in the wrong way which can result in the acceleration problem. How can this happen?
- Well, for example, a pollution error appears on the computer and it might trick it that the car is producing massive amount of fumes.
- So, the ECU is slowly decreasing the engine power in order to fix the pollution problem in the first place. And, that leads to acceleration problems.
However, this is only one example of ECU malfunctioning.
There might be some even more serious problems if your ECU is acting strangely. Not only that your car might have problems with acceleration, but also, it might experience sudden break downs as well.
4) Fuel Filter Problems
Now, the problem with the filthy fuel filter is actually common for a little bit older cars. As we all know, the fuel tank is where the fuel is stored. From the fuel tank, fuel travels to the engine and makes the car move, which is basically acceleration.
But, if you have some sludge in your fuel tank, your engine might get a bit damaged by it. That can cause your car not to accelerate properly.
- There is a bit of sludge in every car’s fuel tank. That might be caused by low-quality fuel or some other things as well.
- Actually, the dirt in the fuel tank makes the fuel heavy and pretty hard to travel to the engine. That is why your car might be experiencing acceleration problems in the first place.
5) Timing Belt Problems
Do you know faulty timing belt is the another reason of accelerating problems. When your timing belt gets damaged after long time uses then you can see this type of problems.
Sometimes, new timing belt is not enough solution. If you can’t place the timing belt properly it happens again.
In the light of everything we said above, a car not accelerating when pressing gas might be caused by several things. We have discussed some of the most common causes of this problem. So, you can see if your car is having troubles accelerating as well.
All in all, acceleration problem is definitely a serious thing to watch out for since that is basically the main car’s performance. All you have to do is to look out for these signs that we discussed.
