BMW 730 idle jitter solution.

Bmw 730: 1 causes of idling jitter. Engine carbon deposit. When the car is driving at high speed and low speed, it will not only damage the gearbox, but also increase the carbon deposition in the engine cylinder, which will consume more fuel over time. 2. Ignition system problem. 3. The oil pressure is unstable. BMW 730 belongs to BMW 7 Series, which is BMW's top luxury car series. Its body is a four-door car, and its driving form is front and rear driving. The BMW 7 Series is the flagship model of BMW.

1. Engine carbon deposit: The most common reason is that the throttle valve is too dirty or the fuel nozzle has too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by the carbon deposit during the cold start, which leads to the lean mixture during the cold start and makes it difficult to start.

2. Ignition system problems: Check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor ignition system and poor ignition conditions of spark plugs can also lead to such failures. The solution is to check the spark plug for excessive carbon deposition and replace the spark plug.

3. Unstable oil pressure: If the carbon deposit in the engine has been cleaned, the throttle valve has been cleaned, the oil pad and spark plug have been replaced, and the body is shaking at idle speed, it is recommended to 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 numerical error and poor work of the intake pressure sensor will lead to body jitter. The solution is to check the oil pressure and replace the parts if necessary. Million car purchase subsidy
