Why Doesn't My Car Accelerate Properly
There are many possible 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 minimize the chances of any of these happening to your vehicle.
In this oneHOWTO article, we can answer why doesn't your car accelerate properly.
One of the most common reasons why your car does not accelerate 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 because of the slipping clutch. You must go to your mechanic immediately to find the exact cause of the problem and fix it.
Timing belt fault
A fault in the timing belt of your car may also be the reason why it is not accelerating properly. This vital part of a car's structure 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. If the timing belt is the slightest bit misplaced, it will show when you accelerate.
However, proper maintenance is essential to avoid situations where the car does not accelerate properly. See this link to find out when to change your car's timing belt.
Dirty fuel filter
Another reason why your car doesn't accelerate properly could be a very dirty fuel filter, which will eventually prevent the fuel from providing the engine with sufficient energy to move. There is an even easier reason related to fuel: it might be that your car isn't accelerating because your petrol tank is nearly empty. Simple, but way too easy to overlook.
Problems in the electronic system
Sometimes, a car does not accelerate due to an error in the electronic control unit, 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 power 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 control unit of the car and you will have to go to a garage that specializes in such problems to get it fixed. Repairing this type of fault is not going to be cheap. This is another common reason why your car loses power, even when you're not accelerating.
Warning from the oxygen sensor
Sometimes, the electronic control unit warning of fumes is not due to an error. If there is not enough oxygen in the engine and the air-to-fuel mixture is unbalanced, the fuel does not burn properly. This causes fumes and pollutants that eventually will damage your car's engine.
The oxygen sensor is in charge of regulating that balance. If there is a problem, it will change the mixture by using more or less fuel. One of the symptoms of not enough oxygen in the engine is problems accelerating.
Blocked or clogged air filter
Another reason why your car doesn't accelerate properly can be that your air filter or exhaust is clogged or even completely blocked. Here you can learn how to clean your air filter at home to prevent such a problem from happening.
Other reasons why your car doesn't accelerate as it normally would can include wiring and sensor issues or malfunctions. Wires and other electrical elements of your car wear down with time, and they can also become loose. This is a big risk, and can cause short circuits and failures in transmitting information to the engine.
A vacuum leak means that an external element like air or fuel enter the engine, which can make the car stutter.
These are some of the most common causes why your car doesn't accelerate properly. However, this is a quite important problem all by itself, so you should bring your car to a mechanic for a complete service.
A car that does not accelerate properly when required can compromise the safety of 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.
If you find that none of the above are the underlying problem of your car accelerating, take a look at how you can make your car accelerate further with these simple tricks that won't compromise the safety of your car or its occupants.
