What does a blocked air filter cause?
A dirty air filter prevents the necessary volume of clean air from reaching the engine which affects the emission control systems of the car; reducing air flow and causing a too rich air-fuel mixture which can foul the spark plugs. Fouled spark plugs can create an engine miss, rough idle and even starting problems.Click to…

Make sure you know the warning signs of a failing filter so you can have a better sense of when it should be replaced. Gas Mileage. Misfiring or Missing Engine. Unusual Engine Sounds. Service Engine Light. Air filter appears dirty. Reduced Horsepower. Black Smoke or Flames Exiting the Exhaust. Gasoline Smell. Similarly, what codes can a dirty air filter cause? A contaminated air filter can restrict engine airflow, resulting in a rich air/fuel mixture. This results in incomplete combustion and an engine misfire. A rich fuel mixture can also foul the spark plugs, causing a misfire. An engine misfire can greatly increase vehicle emissions. Regarding this, what happens if air filter is blocked? If your air filter gets too dirty or clogged, your engine won’t be able to suck enough air into the combustion chambers. The engine will then run rich (i.e., too much gas and not enough air). When this happens, your car will lose power and run roughly. Your Check Engine light also may come on.Can a dirty air filter cause your car to stall?A severely clogged air filter can cause the engine to sputter or even stall. When the engine is unable to draw in an adequate amount of air, it can experience an overly rich air-to-fuel ratio. This leads to an inefficient combustion process, with excess fuel remaining in the cylinders after each piston cycle.
