Failed Catalytic Converter

A catalytic converter is a simple but expensive part of the exhaust system that converts carbon monoxide to carbon dioxide in the combustion chamber. If you hear odd sounds when driving or see discolored smoke from the exhaust, then your catalytic converter may be the cause.

Faulty Spark Plugs

Spark plugs are used to pass electricity from the coil to the spark plug. Without them, the mixture of fuel and air in the cylinders cannot be ignited. Spark plugs should be replaced every few years or every 10,000 miles.

Loose Gas Cap

A loose gas cap is one of the most common triggers for the check engine light to turn on.

Don’t worry, the light should go off after around 15-20 miles of driving. If it does not, you may need to purchase a new one from a nearby auto parts store.

Failing Mass Air Flow Sensor

The mass airflow sensor is a small component that could easily fit on the palm of your hand but is very expensive to replace. It is one of the main parts of your car’s engine as it monitors and calculates the amount of air the engine receives and the amount of fuel injected. A defective mass airflow sensor can cause a dramatic decrease in your car’s fuel economy, as well as poor engine efficiency.

Vacuum Leak

If your car unexpectedly started to accelerate or settle at an abnormally high RPM, then chances are you may have a vacuum leak. The good news is that vacuum lines don’t cost a lot of money. However, the process of finding the source of the leak may be a bit time-consuming.
