Filter Warning Signs

Air filters allow airflow to the inside of the vehicle, it keeps you away from harmful contaminants from the outside environment. Over time, it can get clogged which can be a cause of a problem to the overall performance of the vehicle. These are the warning signs that can make you notice the failing filter.

  1. Gas Mileage: There is a decrease in fuel efficiency since the engine compensates with the low amounts of oxygen.
  2. Misfiring or Missing Engine: As it impedes the airflow to the engine, it results in a highly concentrated mixture of air and fuel thus polluting the spark plugs.
  3. Unusual Engine Sounds: A vibration or a coughing and slipping sound can be heard when the car is on idle.
  4. Service Engine Light: Engine power is combined with a thousand gallons of air and one gallon of fuel thus inadequate air may trigger the service engine light.
  5. Air Filter appears dirty: It accumulates dust and dirt, thus it will appear darker in color.
  6. Reduced Horsepower: Jerking movements occur as you try to accelerate.
  7. Black or Smoke flames going out of the exhaust: Some of the fuel are not burning due to the insufficient supply of air.
  8. Gasoline Smell: An insufficient amount of oxygen enters the fuel ejection system, thus the excess unburnt fuel goes out through the exhaust pipe.

Engine Performance Warning Signs

The system might show warning signs as the engine performance starts to diminish. Keep engine properly tuned up for maximum performance for it is a complicated system that needs a preventive maintenance.

Check Engine Light Activates: As it informs you the engine potential, check if the engine light is flashing that indicates a serious problem with your car system.

Loss of Power: A stemming from a hiccup to any of these strokes– intake stroke, compression stroke, combustion stroke and exhaustion stroke can result in a loss of power.

Drop off of Gas Mileage: Have a fuel cleaner, this indicates that there is a problem with the compression stroke of the engine.

Engine Noise: A sound occurs as you start the engine, a noise of hissing, knocking, spitting, popping and backfiring may be heard.

Engine Stalling: This is a result of the intake stroke not able to receive the right fuel mixture or right spark. This problem is less common with automatic transmission vehicles than manual transmission vehicles.

Unpleasant Odor: From the exhaust, an odor can be smelled due to the exhaust stroke of the internal combustion is about to fail.

After the Ignition is turned off, Engine is still Running: Overreactive fuel ejection system, failing solenoid or an incorrect octane gas is used may be the common cause why this problem happens. This mostly happens with high-performance vehicles which also known as run-on and dieseling.

Rough Running Engine: Incorrect octane, low battery, clogs in the system or old spark plugs might be the reason your engine is rough when running or idling.
