Poor fuel economy

Hello,

There are multiple factors why you might be getting poor fuel economy.
This can range from dirty components to outside factors like the weather.
It can be due to a dirty air filter, or mass air flow sensor. Worn spark plugs. Malfunctioning oxygen sensor. It can also be impacted by getting poor quality fuel.

Many times, performing an engine tune can restore performance and fuel economy.
