Novice throttle

Santana 99 rookie warms up the car in the morning 1000 and starts idling. After a while, the car shook and the idle speed rose to more than 2000 rpm, so he couldn't get off for a long time.

Cause of throttle failure; Too dirty throttle or too much carbon deposit in fuel injector, gear start vibration, cold start and insufficient three-way catalytic temperature are the most common reasons for automobile vibration, because gasoline adsorbed on carbon deposit after landing is sucked into the cylinder by the engine for combustion, and the combustible mixture of the engine is sometimes rare and thick, which leads to idling vibration after cold start. Solution: The company cleans the oil circuit, and checks whether the idle motor has carbon deposit, so it should be cleaned.
