Common problems of nv200 gear shift lever jitter

Normal. Nv200 gear shift lever jitter is normal. It is common to drive for a long time, because the throttle is too dirty or the throttle has too much carbon. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by a large amount of carbon deposit during cold start, which leads to the lean mixture and difficult fuel injection during cold start.
