What causes the rear wheel of the Jog to rotate at idle?

[DelRhett]

The rear wheel of the Jog rotating at idle is caused by a lean idle air-fuel mixture. Reasons for a lean air-fuel mixture: Include excessive air intake, insufficient fuel injection, insufficient cylinder pressure, abnormal ignition, and incorrect sensor input signals. For vehicles with a mileage of less than 50,000 km, insufficient cylinder pressure can be ruled out. Methods to detect a lean air-fuel mixture: Connect a fault diagnostic tool and perform an "active test" on the fuel injector. By manually increasing or decreasing the fuel injection amount to change the air-fuel ratio, then check the oxygen sensor output signal and observe if there is any change. If there is no change, it indicates that the oxygen sensor has failed.
