What's with the engine shaking after stopping for more than three hours in the morning?

Look at your account; A few seconds after the cold car started, the engine shook violently. Check several aspects that are easy to cause this phenomenon. 1. Whether the spark plug in the ignition system has high voltage and weak fire mainly depends on whether the ignition is weak or not, which is mainly related to the spark plug. 2. Is the air intake at idle speed smooth and is there a problem with the idle valve? It's that your wheel is broken. Keep running at high speed. Do a single-wheel dynamic balance after each tire repair. If it's a long-distance high-speed walk, just put the tire pressure at the standard level of about two and a half, with four wheels as many as possible. Then do a four-wheel dynamic balance. If there is a deviation in the vehicle, you should do a four-wheel alignment to repair it. I suggest you look at your front wheel. 1. Engine idling at low speed. 2 Throttle body. Or the air inlet needs to be cleaned. It is recommended to find an electrical appliance to check whether it is still an oil circuit problem. I used to be fine without cleaning. After cleaning, due to the long time and kilometers of your vehicle, the carbon deposit on the top of the piston and the combustion chamber was not cleaned. Just like your own range hood, it feels good to clean it once a day or once a week. If you are optimistic about washing vehicles with more than one kilometer a year, it is recommended to wash them manually. If disassembly-free is used, the initial judgment is that the oil nozzle is leaking. After flameout, the tubing still maintains a certain pressure. If the nozzle leaks oil, the fuel pressure after flameout will cause the leaking nozzle to continue dripping oil, but at this time, the engine stops working and the fuel will accumulate at the air intake. Inhalation of a large amount of fuel during start-up leads to poor ignition of the cylinder, resulting in cylinder-free jitter of the engine. Hello, idling body shake is a common situation for many car owners. If the owner finds that the vehicle body shakes obviously when starting or stopping the vehicle without turning off the engine, it may indicate that the vehicle has the following three conditions: 1. The most common cause of vehicle jitter caused by serious carbon deposition in the engine is that the throttle valve is too dirty or the injector has too much carbon deposition.
