The air and the gasoline fumes mix inside the combustion chamber cylinders, then they will ignite and create fuel for the engine. But the sensors inside the engine can become old or damaged, especially if the vehicle overheats several times. 

When the sensors retain damage, the oxygen numbers that report to the vehicle’s computer will be off. This will happen, even if the right amount of oxygen is in the combustion chamber period. This will cause the vehicle to add even more air into the combustion chamber, which will throw off the gasoline oxygen mixture.
