What are the reasons for the large injection pulse width of the Bora Classic?

[Erin]

Bora Classic injection pulse width is too large for the following reasons: Observe with idle speed: If the injection pulse width is too large, it is generally necessary to observe it in conjunction with the idle speed. If the idle speed is high and the pulse width is large, it is usually caused by false signals from the throttle position sensor or coolant temperature sensor. If the idle speed is normal, then the oxygen sensor is likely to be faulty. Caused by inaccurate closed-loop data: Inaccurate closed-loop data received by the ECU can also lead to this issue. Among these data, the oxygen sensor and coolant temperature sensor are the primary factors, though the intake pressure sensor and throttle position sensor should not be ruled out. Use a Bluetooth OBD scanner to identify the source of the problem.
