How to solve the jitter of mg6 engine?

The causes of engine jitter of MG mg6 are as follows: 1, and the choke is blocked. The solution is to take it down and clean it. The air filter is dirty, and the solution is to replace the filter element. 2. Throttle is blocked by carbon deposit and oil pollution. Check the throttle valve, idle valve and air inlet, and clean with cleaning agent. If the spark plug fails, the treatment method is to replace the spark plug; 3. The idle speed is low. The solution is to increase the idle speed and reduce the cylinder pressure. Check the cylinder pressure with the cylinder pressure gauge, and increase the cylinder pressure when the cylinder pressure is low; 4. The water temperature is abnormal. The fault is due to insufficient antifreeze, the thermostat can't be opened, the fan doesn't turn, and the temperature of the temperature control switch is not allowed. Just get rid of the above faults.
