10 lavida throttle

1, too much carbon deposit in the throttle or engine.

2. When the oxygen sensor fails, the mixing ratio is unbalanced. If you drive at a low speed in the urban area for a long time, it is easy to appear this phenomenon.

3. The nozzle leaks oil, which causes the nozzle to be still in the oil supply state after the throttle valve is closed, resulting in too much mixed gas when driving at low speed, which leads to unstable idle speed after the oil is closed. If it is serious, turn it off directly.

4. The oxygen sensor was poisoned by adding inferior gasoline with excessive metal content. The solution is to change to a gas station.
