What happened when BYD s6 didn't idle after timing change?

The reasons why BYD s6 does not idle after timing change are improper timing adjustment, air flowmeter damage, and throttle or idle control valve damage.

1. Improper timing adjustment: the timing adjustment is not accurate enough, resulting in the engine not running normally, and then the idle speed is unstable or unable to idle. It is necessary to readjust the time.

2. The air flowmeter is damaged: the air flowmeter is damaged in the process of changing the timing, and it is impossible to measure the air flow, thus affecting the fuel injection and air intake of the engine. The air flow meter needs to be replaced.

3. Damage of throttle or idle speed control valve: If these two parts fail, it will affect the air-fuel ratio of the engine, resulting in unstable idle speed or inability to idle. Damaged parts need to be inspected and replaced.
