Why won’t my car accelerate when I push the gas?

Fuel and Air Delivery Problems Poor acceleration can result from an engine that’s running lean (not enough fuel). Similarly, a lack of airflow can also prevent the engine from accelerating as it should. Some of the most common causes of fuel and air delivery issues include: A weak fuel pump.

How do I get rid of acceleration lag?
