19 is there a problem with the low idle speed of Cruze?
Causes of low idle speed
There is carbon deposit on the throttle valve. The maintenance technician opens the engine protective cover, removes the intake hose and throttle valve, and observes whether there is carbon deposit on the throttle valve. If there is carbon deposit on the throttle valve, the throttle valve will not work normally, resulting in abnormal air intake of the engine, which will lead to engine speed fluctuation.
When the oxygen sensor fails, the maintenance technician reads the data stream of the oxygen sensor with the automobile diagnosis computer, and analyzes whether the exhaust data of the oxygen sensor is consistent with the actual situation. If not, the fault can be confirmed. If the oxygen sensor fails, it will not be able to transmit correct exhaust data to the engine computer, resulting in abnormal fuel injection and unstable speed of the engine.
