Why doesn't my Car Accelerate Properly 

There can be many reasons why your car is not accelerating properly. Some are very simple to fix, while others will need a professional mechanic and a considerable amount of money. In any case, it is important to remember that with good maintenance of your car you will minimise the chances of this happening to your vehicle. At we can answer why your car is not accelerating properly.

One of the most common reasons why your car is not accelerating properly is that the clutch isn't properly engaging the gearbox with the engine due to a mechanical error. The result is that the car does not accelerate properly. You must go to your mechanic immediately to check the cause of the problem and fix it.


A fault in the timing belt of your car may also be the reason why it is not accelerating properly. This vital part doesn't tend to cause problems and it doesn't usually get much attention beyond the maintenance carried out by the mechanic during periodic servicing. However, proper maintenance is essential to avoid situations where the car does not accelerate properly. See this link to find out when to change the timing belt in your car.


The reason why your car isn't accelerating properly could also be a very dirty fuel filter, which will eventually prevent the fuel from providing the engine with sufficient energy to produce movement. Check if your fuel filter is bad and, if this is the case, you can learn how to clean your fuel filter here.

It might also be that your car isn't accelerating properly because your petrol tank is nearly empty.


Sometimes the car does not accelerate due to an error in the electronic system, if it has one. For example, the electronic system often warns that the car is producing too many fumes. This makes the car slowly lose strength until it is eventually unable to accelerate, due to what the system has interpreted as a "pollution error". In this case, the fault is in the electronic system of the car and you will have to go to a garage that specialises in such problems to get it fixed. Repairing this type of fault is not going to be cheap.


These are some of the most common causes why your car does not accelerate properly. However, this is a quite important problem so you should bring your car to the mechanics for a complete service.

A car that does not accelerate properly when required can compromise the safety of both the passengers in the car and other drivers on the road. As such it is essential to get a professional to look at the car and fix the problem.

There may be a problem with the clutch. We'd advise you to take it to a professional mechanic so he/she can solve the problem.
