Did Futian vehicles start to shake?

The reasons for the car's initial jitter are: 1, the throttle is too dirty, and the fuel injector has too much carbon, which leads to jitter; 2, the aging of the engine pad will also cause jitter; 3. The cylinder is pressed down; 4. The spark plug was not replaced in time; 5. Engine jitter caused by low fuel pressure; 6. The high-voltage line is broken; 7. The air filter was dirty and the blockage was not replaced in time. The principle of automobile starting is to make the engine transition from the static state to the working state, turn the crankshaft of the engine with the help of external force, start the internal combustion engine, make the combustible gas in the cylinder burn and start the working cycle, and the crankshaft starts to rotate to the engine operation under the action of external force.
