10 Reasons Your Car Is Losing Power When Accelerating

If you’ve had problems with your car and it appears to be losing its acceleration do not worry, you’re not the only one. The issue is one numerous car owners experience however there are a variety of causes that can cause it.

In this article we’ll take a look at the most frequently cited problems that can arise and how to correct it. If your vehicle is causing you trouble lately, continue reading to find out more.

What Causes Loss of Power When Accelerating?

The most frequent reason the reason a car loses its energy when it accelerates is a clogged fuel (or engine air filters). It could also be due to an unrepaired sensor that is causing problems to the mixture of air and fuel, such as the MAF sensor or the O2 sensor.

These are the most frequent reasons for this type of problem, however they are not any possible cause. Here’s a more thorough list of most frequently occurring reasons your car’s power is waning as it accelerates.

1. Clogged Fuel Filter (Both Diesel & Gas)

A fuel filter is the obligation of filtering fuel before it enters the combustion chamber and engine. If the fuel filter is blocked and the fuel can not make it into the engine in the proper amount then the engine won’t function at its peak.

It will be as if you’re losing power as you accelerate. If this occurs the first thing you need to take is to examine the fuel filter.

The fuel filter is situated inside the engine or close to the tank for fuel inside the trunk of your vehicle.¬†If the fuel filter has become blocked or blocked, it can be replaced by a mechanic who’ll charge you a minimal amount.

2. Clogged/Dirty Air Filter (Both Diesel & Gas)

Clean air is essential for the engine for proper operation. The presence of dust and particles may cause damage to parts of the combustion chamber. So the air coming into the system needs to be kept free of dust and other particles. To guarantee this the air filter is installed just before that throttle’s body.

Once the throttle is turned on, air is drawn in and it is then pushed through the specially designed air filter that cleans the air of dirt and other harmful particles. The air filter becomes degraded after a couple of thousand miles, and it is recommended that you have it replaced each time you have one.

3. Clogged Catalytic Converter or Particle Filter

The exhaust is able to remove all toxic and unneeded gasses out of the combustion engine. The faster the exhaust eliminates these gases, then the quicker the engine will be able to restart combustion.

Thus, if the vehicle is able to expel gases more quickly than it creates them, the vehicle will operate quickly and smooth.

If there’s an obstruction like a catalytic converter that is blocked or a blocked exhaust and exhaust, your engine will lose the power.

4. MAF Sensor Malfunction

The Mass Airflow Sensor (MAF) detects how much air that the vehicle needs to accelerate. Once it’s got that number it relays this data to the ECU and it informs the throttle to adjust accordingly.

In the event that your MAF is not working properly and accurately measuring airflow it could result in an enormous loss of power. Sensors may wear out by dust and heat. Cleaning them regularly can enhance their performance.

5. Oxygen Sensor Malfunction (Gas engines)

The MAF detects the quantity of air that enters the engine. Similarly, the oxygen sensor is used to measure the gasses that leave the engine. It’s located within the exhaust tube. If the MAF readings are in line to the readings of oxygen sensors then your vehicle is in good operating condition.

The oxygen sensor affects also the system for fueling, which is why it is essential for it to perform properly for your vehicle to function smoothly.

When the oxygen sensor is damaged, it could result in a rich or lean condition to the engine, which can result in the engine losing the power it needs to accelerate.

6. Faulty Fuel Injectors (Both Diesel & Gas)

Fuel injectors are used to introduce fuel into the chamber of combustion. They perform this by introducing fuel with high pressure, similar to as sprays. They have to apply the exact quantity of the fuel in order to allow combustion to occur.

If there’s even a small error the combustion cycle could be slowed, leading to the loss of power or even, in the worst-case scenario broken pistons or cams.

7. Fuel Pump (Gas Engines)

The fuel pump transfers fuel from the tank into the motor. The pump must be strong enough to to pump fuel with high pressure. In the event that pressures are not high then the fuel injectors aren’t able to inject the right volume of gas into the combustion chamber which can result in an inability to pump the fuel.

A damaged fuel pump should not cause problems at slow speeds, however you may be disappointed when you’re looking for speedy acceleration. Fuel pumps generally have a long lifespan and therefore making sure you check the fuel pump on your vehicle should not be your first choice.

8. Worn Spark Plugs (Gas Engines)

Spark plugs are an additional component of the engine which can create problems for the power of the engine. They generate sparks that cause explosions within the combustion chamber. If they’re not there, the vehicle isn’t able to run at all.

If you’re experiencing power loss and your spark plugs are not working properly, it could be a cause for concern in uncommon situations. Most often, you’ll find worn spark plugs if your car is not running.

If your car’s engine does not sound as usual it is possible that the spark plug has damaged and the vehicle is running with one cylinder less than normal.

9. Poor Cylinder Compression (Both Diesel & Gas)

The cylinders of the engine must be sealed to ensure they are able to contain the explosions occurring within them. The car operates according to this fundamental principle. In the event that compression rates are very high, then all the energy from the explosion is used to propel the pistons. If there’s an issue with the leak and the compression rate decreases, it will be less.

In simpler terms, it means that the cylinder can’t compress the explosion and power isn’t fully transmitted to the wheels. This could lead to an inability to generate power when moving.

10. Faulty Turbocharger / Boost pipe leak (Both Diesel & Petrol)

If your car comes with a turbocharger, the turbocharger may be damaged. The turbocharger provides the engine with lots of additional horsepower and, without it, your car will experience the feeling of the tractor.

Another possibility is that the turbo boost pipe broke and the turbocharger could not boost the pressure of the turbo. This could cause a significant decrease in the performance of the engine and may cause the turbocharger fail.

FAQs

Do bad spark plugs result in an interruption in power?

Yes. bad spark plugs can lead to power loss. If your spark plugs don’t work correctly, it could result in the engine fail and operate inefficiently. If you’re experiencing a decrease in power, make sure you check the state of the spark plugs to determine whether they could be the reason.

What can I do to determine whether my fuel filter is blocked?

There are many ways to find out whether your fuel filter is blocked. One option is to do an inspection visually on the filter. If the fuel inside the fuel filter appears to be dirty or clogged, it’s probably that it has become blocked and must be replaced.
Another way to confirm whether the fuel filter is blocked is to test the pressure of the fuel. If the pressure of the fuel is less than normal this could signal that the filter has become blocked.

Do MAF sensors need cleaning? does the trick?

Yes. A buildup of gunk and dirt on the sensor could cause it to fail and cause the car’s engine to operate badly and to slow down. Cleaning your MAF’s sensor, you’re getting rid of the gunk that has been built up and making it possible for it to work normally once more.

Does an unclean air filter result in lower engine performance?

A dirty air filter could result in diminished engine power. An air filter that is dirty can limit the quantity of air that can be pumped into the engine, which could result in a loss of power. It is recommended to replace your air filter following your vehicle’s scheduled maintenance.

Conclusion

There are numerous possible causes for a car to lose power when it accelerates. It could be like a simple blockage in a air or fuel filter or more serious such as an issue with fuel supply.

The best method to begin finding out if a car has lost power when it accelerates is to check the trouble codes of the control unit for engines by using the help of an OBD scanner.

It is also advisable to check for service bulletins that provide technical information that pertain to your vehicle. For instance, Honda, Jeep, and Ram automobiles have recalls and investigations into power loss.

If your vehicle is experiencing this issue, but you’re not equipped with the expertise to fix it go to a certified mechanic and ask them to identify the issue as quickly as they can. If you can get the right diagnosis and fix the problem, you’ll be capable of getting your vehicle returning to normal functioning smoothly once more.
