Why Is My Car Not Accelerating Properly?

When you apply pressure to the gas pedal in your car, you expect the vehicle to pick up speed and accelerate immediately. There may be issues present if the car starts to slow down and feels sluggish, making it difficult to keep up with other cars on the road. A few main issues can prevent your car from accelerating, which makes it necessary to work with a professional to diagnose the issue and perform the correct repairs.

1. Dirty Mass Air Flow Sensor (MAF) or Oxygen Sensor

The oxygen sensor and mass airflow sensor are both responsible for monitoring the air-fuel mixture in the car. If the sensors get dirty, your vehicle may struggle to accelerate and fail to have good fuel mileage. A professional technician can quickly clean the mass airflow sensor, but the oxygen sensor will need replacement. These problems will make the Check Engine light come on, which will turn off once the parts are cleaned or replaced. A technician can look under the hood to diagnose the problem and perform the repairs you need.

2. Malfunctioning Throttle Position Sensor (TPS)

Your throttle position sensor can affect your car's speed if it starts to malfunction. This makes it difficult for the engine to know how it should adjust as the throttle valve opening angle is monitored.

3. Clogged Fuel Filter

Replacing your fuel filter is necessary if it accumulates too much dirt and grime after a few months. This can cause a lot of impurities to develop and accumulate in the gas tank, which affects your car's speed because the engine doesn't get enough fuel.

4. Dirty Air Filters

Your air filter needs to be replaced after a few months, depending on what the manufacturer recommends in your owner's manual. You may notice your car feels a lot slower than normal if the engine isn't getting enough oxygen. Fortunately, this is a quick and easy fix that will make it easier to get around again.
