Can a bad idle air control valve cause loss of power?

Engine stalling If the idle control valve fails completely, it may leave the vehicle without a source of air to maintain a proper idle. This may result in the engine stalling while operating, and in some cases may result in an engine that will not idle at all, and stalls as soon as it is started.

What does the mass airflow sensor do on a Mazda 3?

The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Mazda 3’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your 3’s ECU.

What are the symptoms of a bad MAF sensor?

Here are the most common symptoms of a bad or failing MAF sensor: Idle Issues – Your 3 may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture.
