Santana 3000, after cleaning the throttle and nozzle, the idle speed is unstable and it costs oil. What should I do? The gear began to shake, the three-way catalytic temperature was not enough, and the engine carbon deposition was serious. The most common reason for automobile jitter is that the throttle is too dirty or the fuel nozzle has too much carbon deposit. Because the gasoline adsorbed on the carbon deposit after the automobile is sucked into the cylinder by the engine, the combustible mixture of the engine is sometimes rare and sometimes thick, which leads to idling jitter after cold start. Solution: The company cleans the oil circuit, and checks whether the idle motor has carbon deposit, so it should be cleaned.
