How to Adjust Idle Speed of Mazda Yi Rui

If you can't adjust the electronic throttle, you can rely on the computer to control the automatic idle speed.

At present, the idle speed of the car is set by the manufacturer and cannot be adjusted. Idle speeds of different cars are not comparable. In the carburetor era, the idle speed of the car can be adjusted, and there are often cars that need to adjust the idle speed, and the valve clearance can also be adjusted. When the valve clicks, it must be adjusted.

With the progress of science and technology, it is now irreconcilable to reduce the maintenance items of cars. Whether it is electronic throttle or cable throttle, idle speed is self-adjusting.

Due to the influence of carbon deposition, the idle speed will change. Take the electronic throttle as an example. After the throttle is completely released, the electronic throttle will not be completely closed, and there will be a certain gap for air to pass through, which is the air needed for idling.

If there is carbon deposit, it will block some gaps and the amount of air entering will be less. If no measures are taken, idling jitter or even flameout will occur. At this time, the engine computer will control the throttle to open a little gap, so that the air intake will be more and the normal idle speed can be maintained. Although the computer can control the throttle to adjust the idle speed, of course, it will not be infinitely adjusted, only a small adjustment range. Adjust it to the limit, or the car will break down.
