Buick Hideo started shaking, didn't idle, what happened to the flameout?

This situation is mostly due to the excessive carbon accumulation in the engine cylinder, which leads to the adsorption of a large amount of fuel when the cold car starts, resulting in unbalanced mixture, unstable idle speed and flameout. It is necessary to clean the carbon deposit in the cylinder and the carbon deposit in the air inlet. If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
