5 different scenarios of why this might be:
1. Evaporative System.
The evaporative system is a very complex system. Typically a loose or faulty gas cap fails to maintain pressure in the engine, which in turn can throw off your diagnostic system. This could cause fuel vapours to leak.
2. Oxygen Sensor.
The monitoring of the oxygen sensor is vital to your vehicle. This monitors the percentage of unburned oxygen in the exhaust to help monitor how much fuel is burned. If this small fixed is left unattended, it could result in a very costly problem.
3. Catalytic Converter.
The catalytic converter is an environmental control device to reduce exhaust gases. If for some reason this is damaged, then you will notice a decrease in gas mileage. Your vehicle will also fail its emissions test.
4. Mass airflow Sensor.
The MAF sensor measure the amount of air coming into your engine. This tells your vehicle how much fuel is needed. If damaged this can cause damage to oxygen sensors, spark plugs, or catalytic converter. Also it can decrease efficiency, increase emissions and cause your vehicle to stall.
5. Spark Plugs and Wires.
The wires and plugs are responsible for creating the original spark that ignites the air/fuel mixture inside cylinders of your vehicles engine. When the plugs are failing your engine will not perform at peak efficiency.
