Is an Idle Speed of 900 RPM Normal for the Lavida?

[OMiles]

An idle speed of 900 RPM is normal for the Lavida. Normal Idle Speed for Small Cars: For typical family compact cars, the idle speed after the engine has warmed up usually ranges between 700-900 RPM. This depends on various factors such as engine displacement, oil viscosity, normal operating temperature of the engine, cleanliness of the intake tract, and fuel quality. Reasons for Cold Start Idle Vibration: Starting with cold starts, the main reason for vehicle vibration during cold starts is incomplete fuel combustion, which results in insufficient power output. Lower ignition energy requires more throttle input to meet power demands during startup, especially when fuel and lubricant temperatures are low. Over time, the electrode gap in spark plugs gradually increases, leading to reduced ignition energy and poor fuel atomization, which causes vehicle vibration. Additionally, aging ignition coils, deteriorated high-voltage spark plug wires, or electrical leakage can also result in decreased ignition energy.
