How to reduce the idle speed of gasoline pump

The method of reducing the idle speed of gasoline pump is as follows:

1. Find the idle adjustment screw on the car engine. It is usually located next to the throttle, and sometimes it may be behind or in front of the air flow meter.

2. Turn the idle adjustment screw slightly to reduce the airflow. If more adjustment is needed, you can adjust the idle flow more finely by turning the screw with a wrench. This usually requires several fine-tuning to get the correct effect.

3. After adjusting the idle speed, it is necessary to wait for a period of time so that the system can relearn the readings of the air flow meter and other sensors. If it is necessary to test the adjustment effect, you can start the engine in the gear or neutral position where the car is at a very low speed, ensure that the throttle does not open, and observe the working effect of the engine.
