Question

What does this selinoid do and does it affect mpg?

Answer 1

Hi there,

The air injection solenoid adds air to the fuel as it goes into the intake manifold. This might cause a reduction in the fuel mileage because the fuel mixture won't be as lean, and also because it won't atomize the same. As a general rule you won't feel any difference in the way the car actually is running.
