2.7 What is the reason for the shift jitter of Xinshengda displacement?

It is recommended to clean the oil circuit, including detecting the spark plug, throttle, gasoline filter, fuel nozzle and nozzle skirt.

There may be the following reasons:

1, cylinder loss, uneven ignition, ignition system failure, some cylinders can not be ignited in time. The exhaust sound will also change.

2, shock absorption aging, loose claws, improper engine fixation. Open the hood and step on the accelerator, and the engine speed will become stable after it rises.

3. The frame is too loose. Some old cars, whose carriages are too loose, start to shake as soon as they start.

4, poor oil quality, premature ignition. Inferior fuel can't reach the label, and the combustion is not good, which leads to engine jitter. Increasing speed will not improve.

5. The engine accessories are loose. At the same time, there will be abnormal noise.
