Car Not Accelerating
 

If you drive your car regularly, you get a good sense of how it typically performs. Therefore, you may be surprised to find one day that the vehicle doesn't seem as responsive as usual when you step on the gas pedal. There may be several different reasons why your car's performance is declining. Most often, the problem arises when a component in the mechanical or fuel line system becomes dirty. You can troubleshoot your car's underlying problem by considering the four common issues below. However, you'll want to visit a mechanic for a final diagnosis and fix.

Dirty Oxygen Sensor

Your car has several sensors in its mechanical system. Either or both of the sensors may become contaminated with debris such as dirt, dust, and other particles in the environment. One component that can become dirty is the oxygen sensor. The oxygen sensor usually monitors the air and fuel mixture in your car. If it gets dirty, it can't keep track of the ratio of fuel and air in the car's system, impacting fuel economy and general performance. Another part that may become contaminated and need replacement is the mass airflow sensor. The mass airflow sensor can also cause a decline in performance if it gets dirty. Along with poor acceleration, you may notice a "Check Engine" light on the dashboard with both of these problems.

Malfunctioning Throttle Position Sensor

Poor acceleration can also be caused by a problem with the Throttle Position Sensor or TPS. The TPS keeps tabs on the opening angle of the throttle valve. The TPS directs the engine to respond based on the opening angle. If the sensor can't determine the valve's opening angle, it may provide the engine with inaccurate information that impacts the car's performance.

Clogged Fuel Filter

The fuel filter is one of two filters that the car's engine uses. The fuel filter has the critical task of preventing dirt, dust, pollen, and other small particles from reaching the engine and, in turn, causing contamination. If the fuel filter gets clogged, it won't filter out particles, which causes the car's performance to suffer. A clogged filter usually needs to be replaced.

Dirty Air Filter

The engine also has an air filter that can get dirty and reduce engine performance. An engine that is not functioning properly will, in turn, affect acceleration. Decreased air to the engine also affects gas mileage.

Audi Demonstrates C-V2X Technology for Road Safety

Audi Demonstrates C-V2X Technology for Road Safety

Audi of America, Inc. teamed up with Oceanside, California. It demonstrated how its C-V2X technology could help reduce cyclist injuries and fatalities. The technology allows cars to communicate with each other and with traffic lights. It provides drivers with real-time information about their surroundings. It can help drivers avoid collisions with cyclists, pedestrians, and other vehicles. Audi is one of the first automakers to develop and test C-V2X technology. The company is committed to making its vehicles as safe as possible for all road users.
