Car Not Accelerating

Driving a car that doesn't accelerate like it should is not just annoying but potentially dangerous. You don't want to be struggling to go uphill in a sluggish vehicle, nor do you want to fail to reach the proper speed when you're merging onto a highway.

There are several reasons why your vehicle isn't accelerating properly. While some of those are signs that you have more severe problems with your car, others are relatively easy to diagnose and repair. We're going to take a look at four of the more common reasons for a sluggish vehicle and what you can do to fix them.

A Dirty Mass Flow Sensor or Oxygen Sensor

Your mass flow sensor and oxygen sensor are responsible for monitoring the air-fuel mixture in your vehicle's engine. If these sensors are dirty, it will cause the mixture to be off, which will affect the overall performance of your car. It could affect your acceleration, and it will almost certainly affect your gas mileage. The good news here is that dirty sensors will cause your "Check Engine" light to turn on, so you should know when you have a problem before things go too far. A dirty mass flow sensor can be cleaned by a professional, but an oxygen sensor will need to be replaced.

A Malfunctioning Throttle Position Sensor

Your car's throttle position sensor or TPS is responsible for monitoring the throttle valve angle. When it isn't working properly, it sends the wrong information to your engine's computer. Without the proper data, your computer won't be able to make the necessary adjustments to your engine to keep your vehicle running at its peak efficiency. This problem is a little too difficult for most vehicle owners to repair, but a skilled mechanic will help you.

A Clogged Fuel Filter

The fuel filter keeps dirt, sludge, and other impurities out of your engine. When it fails to do its job, your car will start to feel sluggish. If it is clogged completely, the engine won't receive the fuel to function correctly. Replacing the fuel filter will fix this problem.

Dirty Air Filters

A dirty air filter will prevent your engine from getting enough airflow, which will affect its performance. Air filters need to be replaced regularly, so check your vehicle's manual to know how often you need to change your filters.
