Car Not Accelerating


Most of the time, your Ford responds smoothly and quickly when you step on the accelerator. However, as you're driving around, you may start to notice that the car seems to be sluggish and slow to respond after you step on the gas. Regular maintenance can help avoid many problems that affect acceleration, such as keeping the sensors and filters clear. If you're wondering what could be wrong with your car, we can fill you in on some of the most likely causes.

Dirty Oxygen Sensor or Mass Air Flow Sensor

Your vehicle's engine has several different sensors that allow it to operate correctly. Two critical sensors for the engine's performance are the oxygen sensor and the mass airflow sensor. The oxygen sensor can get dirty if it is not adequately cleaned and replaced as needed. If the oxygen sensor is covered in dirt, it can't regulate the engine's amount of air and fuel. A proper ratio of both is required for optimal vehicle performance. The mass airflow sensor can also get dirty, preventing it from providing the engine with enough air. Along with sluggish acceleration, dirty sensors can trigger the "Check Engine" light on the dashboard.

Malfunctioning Throttle Position Sensor

The throttle position sensor is another component that can stop working properly and cause problems with the car's acceleration system. The throttle position sensor is connected to the throttle valve on the vehicle. The sensor monitors the valve's opening angle to determine how the engine should respond. If the sensor can't detect the throttle position properly, it won't provide accurate information to the engine's computer, which then causes a decline in the car's overall performance.

Clogged Fuel Filter

The main role of the fuel filter in any engine is to trap possibly harmful pollutants that may be in the fuel before they get to the engine. The fuel filter can get dirty and fail to shield the engine from sludge, dirt, dust, and other debris. If the fuel filter is dirty, clean fuel can't reach the engine, which means that the engine won't function properly. Replacing the filter solves the problem.

Dirty Air Filter

Air filters also play a crucial role in optimal engine health and performance. The air filters should be changed regularly to ensure the engine gets enough air. Otherwise, the car won't be able to accelerate and reach its top speed quickly.
