What should I do if Haorui 1.4t starts shaking?

There are many reasons for car jitter. First, clean the throttle and fuel nozzle, and then check the spark plug and ignition coil. The leakage of the ignition coil is not easy to check. The tire pressure is different, the speed is high, the car will shake, and the tire will be dynamically balanced; Finally, check the oil pipe and gasoline filter. Of course, the quality of oil and carbon deposition can also cause car jitter.
