Mitsubishi Jin Xuan 1, 61000 km needs to clean the throttle.

Dirty throttle and fuel injector will cause the phenomena of weak acceleration, loud noise, high fuel consumption, car shake and so on, which need to be cleaned regularly.

The correct way: If there are no abnormal phenomena such as car shaking, there is no need to clean it.
