What is the abnormal engine jitter of Maserati?

There are many reasons for abnormal engine jitter when driving in Pacific Auto Network, such as damaged spark plugs, poor fuel quality, excessive carbon deposition and unstable oil pressure. After a certain mileage, the dirty throttle will cause the throttle to be closed loosely or the idling stepping motor to be stuck. Both of these situations will lead to the engine idling too fast, and the carbon deposition generated by the engine during work will also cause the vehicle to shake.

There are many reasons for abnormal vibration of the engine during driving, such as damaged spark plugs, poor fuel quality, excessive carbon deposition, unstable oil pressure and so on.

1, the spark plug is damaged, and the wear of the spark plug gap will lead to insufficient ignition quantity, and then insufficient combustion of mixed gas, which will lead to jitter when the car accelerates. There are cracks in the ceramic part of the spark plug, which will cause the spark plug not to ignite, and one cylinder will also lead to accelerated jitter. At this time, the spark plug should be replaced. 2. Poor fuel quality Poor gasoline quality will lead to poor atomization effect of the injector, and insufficient combustion of the mixed gas in the cylinder will also lead to engine jitter. It is recommended to use high-grade gasoline after using this box of gasoline and do a fuel system cleaning. 3. Too much carbon deposit, too much carbon deposit in the fuel nozzle and too dirty throttle will lead to the throttle not being closed tightly or the idling stepping motor being stuck after a certain mileage. Both of these situations will lead to the engine idling too high, and the carbon deposit generated by the engine in the working process will also lead to vehicle jitter, especially when starting the vehicle, the engine jitter will be more serious than usual, and even the phenomenon that it can't be started once may occur. Therefore, when the vehicle is shaking, first check the throttle and throttle. If the throttle valve is found to be too dirty or the fuel injector has too much carbon deposit, it should be cleaned in time. 4. The oil pressure is unstable. If you have cleaned up the carbon deposit in the engine, changed the oil and replaced the spark plug, you still find the body shaking at idle speed. I suggest you go to the 4S shop to check whether the oil supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal or the value of the intake pressure sensor is incorrect or works badly, it will cause the body to shake. At this time, check the oil pressure and replace parts if necessary.
