Is the throttle body and idle motor of the engine dirty?
Fault Diagnosis: True Fault
Reason Analysis: Currently, the idle speed of the car engine is controlled by the idle stepper motor installed in the throttle body. When the engine is running, due to air quality and gasoline quality factors, a large amount of dirt will accumulate on the throttle valve and idle valve of the engine throttle body. When the dirt is severe, the engine will experience excessively low idle speed, poor stability, or no idle speed, and the valve will have a sticking phenomenon during refueling. Therefore, after the car has generally traveled about 20000km, it is recommended to clean the throttle body or replace it, and then the engine should be set through a diagnostic instrument to achieve a normal working state.
