Why Is My Car Not Accelerating Properly?

It can be easy to take your car's reliable operation for granted as you spend time getting around. When the vehicle fails to accelerate, it can be difficult to maintain your speed on the highway and stay safe. If your car doesn't reach higher speeds, you may struggle to get to where you need to be on time. There are a few top reasons your car won't accelerate when you put extra pressure on the gas pedal.

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

Your dirty mass airflow sensor or oxygen sensor can both accumulate too much grime and dirt over time. This can prevent your car from getting good fuel mileage or accelerating correctly. If the issue is with the oxygen sensor, it will need to be replaced. If the problem is with the mass airflow sensor, it can be cleaned by a qualified technician. Both of these parts will cause the Check Engine light to turn on if they experience issues. You'll need to reach out to a technician at our dealership to restore the car's operation.

2. Issues with the Throttle Position Sensor (TPS)

You can start to have poor acceleration if there are issues with the Throttle Position Sensor or TPS. This sensor monitors the throttle valve opening angle and influences how well the system adjusts. The car can have a lack of performance if it's only getting inaccurate information.

3. Clogged Fuel Filter

Your car's fuel filter can prevent the vehicle from reaching higher speeds if it gets too dirty. There may be a build-up of sludge and debris, which prevents the engine from getting enough fuel. This requires replacing the filter, which is quick and easy to do with the help of a mechanic.

4. Dirty Air Filters

Read your owner's manual to determine if the air filters have been in place for too long and if you've neglected to replace them. This will affect the car's acceleration because the engine won't be getting enough air or oxygen. The owner's manual will tell you how often you need to replace the air filters.
