Car Not Accelerating
 

Over the lifetime of a vehicle, owners may notice a drop-off in performance. The car just doesn't accelerate like it once did. This may be hard to detect, as the effects can build up slowly over time. This problem is about more than performance and efficiency; it can be a safety issue. Not being able to get up to proper speed can cause accidents. Here are four common reasons for acceleration problems.

1. The Air Filter Needs Changing

Fuel-burning engines require a constant supply of airflow to work properly. Air filters protect your engine from dust and debris. Over time, these particles build up on the filer itself. This can gradually decrease the efficiency and horsepower of the engine. This is a common reason for slow acceleration.

Air filters need to be changed every 15,000 to 45,000 miles depending on the make and model of your vehicle. Consult your owner's manual for exact details on how often to change this part. Fortunately, this routine maintenance job is not expensive.

2. A Clogged Fuel Filter

A clogged fuel filter causes problems in a similar way to a clogged air filter. The fuel filter sifts out dirt, sludge, and contaminants in your fuel to protect the engine. As the fuel filter becomes clogged, it will allow less pure fuel through to the combustion chambers. This once again means less horsepower and sluggish acceleration.

3. Throttle Position Sensor Malfunctions

The Throttle Position Sensor is another common culprit for slow acceleration. This one may cause a warning light to display on your dashboard. This sensor makes sure the correct blend of fuel and air is getting to your engine. When that balance is off, you will often get slow acceleration and poor overall performance.

4. More Sensor Problems

If it's not a filter, then it's likely a sensor. If it's not a Throttle Position Sensor, it may well be the Mass Air Flow Sensor or the Oxygen Sensor. The Mass Air Flow Sensor and Oxygen Sensor are two more parts responsible for the correct air-to-fuel ratio in your engine. If these parts fail, the result will be much the same as having a bad Throttle Position Sensor.
