Common air filter problems


Common air filter problemsAn air filter can have a significant impact on the performance of your car. The use of a clean and correctly installed air filter enables a vehicle to achieve better fuel economy, reduces emissions, and boosts acceleration. This is impressive considering how neglected this component is. Air filters should be replaced every 12 months or every 12,000 miles (roughly 19,000 km) to prevent any problems. Here are some common air filter problems.


Check engine light comes out

You need to take your car to a trustworthy workshop as soon as the check engine light comes on.


Strange engine noises

A smooth engine vibration should be felt and heard while your car is idle or stationary. If you hear unusual noises, such as loud popping, coughing, or spitting, it usually means the engine lacks the proper amount of airflow, which means your air filter needs replacing.

The problem with your engine is a dirty or clogged air filter. When this happens, the air-fuel mixture changes. Black soot residue forms on the spark plug when the rich fuel mixture is burned. These residues prevent the spark plugs from firing properly, causing the noise. You can also experience problems starting your car when the spark plugs are dirty.


Bad smell

Fuel odour is the result of insufficient air entering the fuel injection system and unburned fuel exiting the car through the exhaust pipe (hence the smell). This problem should be resolved by replacing the air filter.


Decreased fuel economy

A bad or dirty air filter results in significantly reduced fuel economy. If the air filter is bad or dirty, it restricts airflow, thus lowering the oxygen level. To compensate for this, your engine consumes more fuel to produce enough power to move the same distance or speed as you could with a clean filter.


Decreased performance

Are you able to press the accelerator normally in your car? Does it seem slow? If it does, your air filter is probably preventing your engine from receiving the clean air it needs to perform optimally.
