Mass Air Flow Sensor

The mass air flow sensor monitors your exhaust flow before and after the catalytic converter. Then, it sends that information to your engine computer which adjusts your fuel injection level, if necessary. If it isn’t working like it should, your fuel efficiency will suffer.

Oxygen Sensor

Your oxygen sensor helps regulate the air-fuel ratio in your engine. If the readings are off, it can cause your vehicle to use more fuel than necessary.

Bad sensor warning signs include:

  • Black exhaust
  • Exhaust has a sulfur smell
  • Poor fuel efficiency
  • Check engine light is on

Spark Plugs

Your spark plugs ignite your engine’s air/fuel mixture to help move your car forward. If they aren’t working properly, your gas mileage will suffer. In fact, faulty spark plugs can affect your fuel efficiency up to 40-percent.


Did you know your tires can also affect your gas mileage? If your tires are underinflated, misaligned, or have extreme wear, it can lead to drag. This forces your engine to work harder than necessary, which also means your engine will use more fuel than necessary too.

Air Filter

Your air filter helps keep contaminants out of your engine. However, when it becomes too clogged, it keeps air from flowing into your engine too. If your air filter has become too dirty or clogged, make sure to have it replaced as soon as you can.
