Drop by and see us today, and let us see if we can help you out.

Loose or Broken Fuel Cap

A loose or broken fuel cap is one of the most common reasons why every engine light switches on. However, the gas cap prevents gasoline fumes from escaping the fuel tank and also ensures that the vehicle system is under the correct pressure. This makes it a vital part of the vehicle’s fuel delivery system. If you note that the check engine light turns on after filling the gas tank, make sure the cap is firmly screwed on or check if it needs to be replaced.

Bad Spark Plug Wires

Spark plug wires are used to pass electricity from the coil to the spark plug. The air and fuel mixture in the cylinders would not be able to fire without these wires. Although some cars use a single wire per cylinder, others use two spark plugs per cylinder, requiring two wires.

Mass Airflow Sensor Failure

The mass airflow sensor is a vital component of the engine as it measures how much air your car’s engine is intaking. Without this sensor, the vehicle will be unable to react to any airflow adjustments. If you experience a rough idle, stall, or have trouble starting your engine, you may need to replace your MAF sensor.

Aftermarket Alarm Issue

Although aftermarket alarms are awesome, they can sometimes cause your car problems if they are not correctly mounted. From exhausting your battery to stopping your vehicle from starting, aftermarket alarms can even cause the check engine light to turn on.

Catalytic Converter Failure

The catalytic converter is a part of the vehicle’s exhaust system and transforms carbon monoxide into carbon dioxide. The good news about this part is that it’s pretty easy, and complete failure can sometimes be avoided.
