A car that runs rich causes higher fuel costs, a poorer driving experience, and a worse environmental impact. Running rich occurs if there is an issue with your engine’s combustion process, meaning your engine is burning too much fuel in relation to the amount of air it takes in. This can cause decreased fuel economy, increased emissions, and engine damage. The most common causes of your engine running rich are a faulty MAF sensor, O2 sensor, or MAP sensor.

What You'll Learn
Engine running rich is burning too much fuel
An engine running rich is burning too much fuel in relation to the amount of air it takes in. This means that the air-to-fuel ratio is off, with too much fuel and not enough air. This can cause several problems, including decreased fuel economy, increased emissions, and engine damage.
When a car is running rich, it means the engine is injecting too much fuel and too little air for perfect combustion, a rich air-fuel mixture. This will not only lead to a high fuel consumption bill, but it can also cause damage to costly parts like the catalytic converter if you are unlucky.
The most common causes of your engine running rich are a faulty MAF sensor, O2 sensor, or MAP sensor. It can also be caused by a faulty coolant temp sensor, IAT sensor, or a faulty fuel pressure regulator.
One of the symptoms of an engine running rich is that you do not get the right gas mileage. This is because the car does not need all the fuel being supplied. However, it is normal to spend more on gas during winter or when carrying heavy loads. For your car’s engine performance to be normal, there has to be the right amount of fuel/air mixture.
A car that runs rich causes a few problems: higher fuel costs, a poorer driving experience, and a worse environmental impact.
