If you notice that your vehicle doesn’t accelerate well, or simply doesn’t have the power that it used to, there’s a good chance that the air filter is not allowing enough air into your car’s engine. Your car needs fresh air for the combustion process, and a dirty air filter prevents the intake of enough air. You also may notice jerky acceleration with the pressing of the gas pedal on your vehicle. This also is a common sign of a dirty air filter.
A dirty or clogged air filter often leads to many strange noises when the car is idling. If you notice coughing or spitting type noises when your car is stopped in traffic, this is a good sign that your car’s engine is not receiving adequate airflow and that the air filter needs to be changed.
