If your car’s engine is idling rough or stalling, it could be a sign that the idle air control (IAC) valve is malfunctioning. The IAC valve is a small but important part of your engine that helps regulate the idle speed. When the engine is idling, the IAC valve opens to allow air to bypass the throttle plate and enter the engine. This helps to keep the engine running at a steady speed.
The idle air control valve is a small, solenoid-operated valve that is mounted on the intake manifold. It is controlled by the engine’s computer, which uses sensors to monitor the engine’s speed and load. When the engine is idling, the computer opens the IAC valve to allow air to enter the engine. This helps to keep the engine running at a steady speed.
If you are experiencing any of the symptoms of a bad idle air control valve, it is important to have the valve checked by a qualified mechanic. The mechanic will be able to diagnose the problem and replace the valve if necessary.
