When you’re driving, the car’s idle is a key part of your driving experience. It’s the time between when the engine is running and when you can finally start the car. To adjust your car’s idle, first make sure that your car has a Idle Air Control (IAC) system. This system helps to keep your engine running at a consistent speed while you’re driving. Next, make sure that your idle speed is set at a comfortable level for you. This will help to keep your engine running at its best while you’re driving. Finally, make sure that your IAC system is working properly by checking it every time you start the car. If it isn’t working correctly, then you’ll need to replace it with a new one.
