How to adjust the idle speed of Alto?

New Alto uses computer to control the idle speed, and cannot manually adjust the idle speed. Abnormal idle speed is a sign that the throttle is dirty. After cleaning the throttle, the idle system will automatically return to normal. The specific operation steps of cleaning are as follows:

1. Remove the new midrange throttle hose.

2. Open the new Alto throttle.

3. Clean the new Alto throttle with a brush.

4. Spray with detergent.

5. Replace the hose and it's done.

Idle speed grade

1, normal idle speed

When the vehicle is parked and the engine is started, the lowest rotation speed of the engine running stably is called parking idle speed (the process that the engine changes from the idle state of cold car to the idle state that the engine reaches the normal working temperature is called warm car or hot car).

2. Driving at idle speed

When the car is in gear, the minimum opening of the throttle valve remains unchanged, and there is no need to step on the accelerator pedal or loosen it when driving. At this time, the engine speed is consistent with the parking idle speed, which is called driving idle speed.
