Fei Xiang 12 automatic exclusive version will shake like it is going to turn off after driving 80 yards. Why?

From the point of fault classification, it can be divided into circuit fault, oil fault and mechanical fault. The other is human failure. The detailed analysis is as follows: 1, the air filter is blocked or water enters, at this time, the air intake is not smooth, and the oil supply is not smooth, resulting in sudden acceleration jitter. 2. There is water in the fuel, the filter element has not been replaced for a long time, and the oil quality is not good. In another case, the gas station just filled up the fuel tank and didn't settle the bill. As soon as you went to refuel, the water in it was impulsively added to your fuel tank. Individual gas stations refuel (oil storage equipment is not up to standard). 3. Mechanically, too much carbon deposition on the throttle, excessive wear of the timing belt (gear), and wear of the timing gear sleeve and the random gear sleeve cause the ignition timing to be delayed or advanced. Excessive wear of the piston or valve in the engine cylinder head causes the cylinder pressure to fail to meet the requirements. 4. In terms of circuit, various sensors, especially oxygen sensor and throttle position sensor, have great influence. Of course, most circuit faults will be accompanied by the lighting or flashing of the instrument engine fault light. The spark plugs of individual cylinders are not working properly or do not work, and the circuit is out of order.
