Car Not Accelerating

 

There are several reasons why your car might not be accelerating properly. We're going to talk about the four most common causes and how they can be fixed. These are relatively minor issues that can be remedied easily, but they should still be addressed before your vehicle's sluggish performance becomes a severe problem.

A Dirty Mass Airflow Sensor or Oxygen Sensor

The mass airflow and oxygen sensors control the air-fuel mixture in your vehicle. They don't function very well when they get too dirty, which will impact your car's overall performance. A dirty mass airflow sensor can be cleaned by a repair professional, while a dirty oxygen sensor will need to be replaced.

A Malfunctioning Throttle Position Sensor

The throttle position sensor monitors the throttle valve opening angle and relays the data to your engine's computer so it can adjust your engine accordingly. If it malfunctions, your computer gets the wrong data and cannot make the proper adjustments. This leads to problems such as poor gas mileage and sluggish acceleration. This is a relatively quick fix, but it is also complicated enough that you should leave it to a repair professional.

A Clogged Fuel Filter

The fuel filter is what keeps sludge, dirt, debris, and other impurities out of your fuel. It also tends to prevent your engine from getting the fuel that it needs when it gets clogged. Replacing the filter should fix the problem.

A Dirty Air Filter

A dirty air filter will prevent your engine from getting enough airflow, affecting your gas mileage and your acceleration. Air filters need to be replaced regularly. This is often when you bring your vehicle in for an oil change, but check your owner's manual to learn how often your filter should be changed.
