What To Do When Your Car Won’t Accelerate While Turning?

It’s hard to identify the major issues with your vehicle. A car’s acceleration problem is harder to find. If you are experiencing this problem and are having trouble locating the causes, here are more causes and steps to overcome.

In this article, learn what to do when your car won’t accelerate while Turning and got your car running again.

What To Do When Your Car Won’t Accelerate While Turning?

When you cannot accelerate remain calm and panicking while driving and put on your hazard lights to alert around you. Then find a safe place to remove yourself from the road. This could be the shoulder of the load if it will not pose a hazard to the drivers, a public parking lot, or turn out of the road.

In this case, you can call for two or roadside assistance,  especially if your vehicle runs under the speed limit to be safe.

What Causes My Car To Not Accelerate?

The main symptoms of a car not accelerating like it used to can occur because of high mileage vehicles. A driver might not notice these signs while driving day or night. But while driving on steep hills or fastening the accelerator in traffic the driver can identify these problems.

1. Oxygen Sensor Malfunction

An oxygen sensor also called an O2 sensor is a device whose function is to monitor the exhaust emission of the vehicle so that it can analyze the air-fuel ratio going through the engine of that vehicle. These gases contain a lot of difficult elements in, such as CO2 and O2.

The internal combustion engine of your vehicle will always produce exhaust gases after the air and the fuel mixture has got ignited in its cylinders. In the exhaust manifold, there is a compound called an oxygen sensor. This sensor keeps oxygen levels in these exhaust gases as they leave the engine. This oxygen gas did not get burnt during the original air and fuel combustion.

After this process, the oxygen sensor detects the level of oxygen, it sends this information back to the engine control module, which is the computer that manages all the systems in the vehicles and communicates with the variety of different sensors that are in the vehicles.

When the engine module receives information about the oxygen level in the exhaust gases. In this case, you came to know the reason, that is the engine may burning too much fuel or too little fuel. For instance, if there is more air than fuel in the chamber cylinders, this will cause lean combustion to take place.

The exhaust gases that give out from such combustion will have more oxygen in them. Once the oxygen sensor detects this and transmits the data to the engine control module, then the computer will make the proper adjustments to the timing of the fuel injectors and the operation of the engine. In this, the air and fuel mixture in the engine will be at its best for combustion purposes.

2. Dirty or Clogged Fuel Filter

A dirty or clogged fuel filter is another reason for a car not accelerating properly like it’s supposed to when required to do so. If the fuel is full of dirt, it won’t allow the vehicle to accelerate. Everybody loves a good car that starts and runs smoothly.

In physical life, people won’t drink the unfiltered water directly from the stream. Because the water may contain harmful bacteria or other microorganisms. Similarly for fuel, thankfully the engine filters the unfiltered fuel, in this case, the debris may remain and you will face the problem.

Symptoms Of Clogged Fuel Filter

The most common signs of clogged fuel filters include starting the engine, a check engine light, or even reduced performance. You may also notice the engine stalls or misfires while accelerating.

In this case, the fuel replacement costs range between $50-$150 at a shop. If it is a local mechanic may cost you about $15-$60.

3. Clogged Or Dirty Air Filters

Alike the fuel filter provides the engine with clean fuel, an air filter provides the engine of a vehicle with the clean air to be used in the air-fuel mixture which will be sent to the combustion chambers to burn.

If an air filter is clogged, this may lead to slow down the acceleration. In the engine won’t get the right air fuel, replace your air filter as soon as possible.

4. Malfunction Of TPS

The basic principle of the throttle position sensor (TPS) is to detect the throttle valve opening angle which is controlled by the accelerator pedal. The throttle position sensor(TPS) will send this data to EUC.

If the TPS malfunctions, the engine speed may not be controlled by the accelerator pedal and the engine speed will increase or decrease without any press being depressed.

Some Of The Mechanical Issues

  • A worn timing belt or chain that has ” jumped a tooth”, knocking spark timing out of sync, will cause reduced power and acceleration problem. The timing belt should be fixed by your mechanics.
  • If your car not accelerating properly, you have to check your vehicle immediately, with your professional mechanic. In this case, if you continue to go drive your vehicle may cause major problems or expensive repairs.

Why Is Driving Too Slowly Dangerous?

While driving a reasonable slower speed is not usually an issue, there are minimum speeds that you should avoid impeding traffic. So you should not ignore the problem for long.

According to various laws, driving too slow leads to dangerous issues more than speeding. Mostly slow drivers force speed drivers to adapt to them and this leads to increased rates of accidents. Chiefly, if they have to land change or slow down and accelerate to accommodate your speed.

It is so dangerous, that in many states, it is considered a non-crime traffic violation. Even you could face a traffic ticket and fines for driving slowly. According to the insurance information institute, a traffic violation can also lead to increased insurance fines.

Worse, this also means there is a serious issue in your vehicle, and they could cause an accident at any time.


There are the causes and symptoms of when a car will not accelerate when turning. The car will not accelerate properly or hesitates and should be inspected and repaired immediately. Continuing to drive with this sort of trouble can be rather dangerous.

Even if the engine troubles are as simple as replacing the air filter. It’s better to err on the side of caution than to risk your safety. Seek out a trusted, professional mechanic to diagnose your vehicle and find what is causing your vehicle’s accelerator problems to have it repaired properly.
