What is the reason for the jitter of idle steering wheel?

The main reason of idle steering wheel jitter is that engine jitter is transmitted to the steering wheel, which is caused by the following reasons: 1. Throttle carbon deposition is serious. 2. Add inferior gasoline. 3. Spark plug failure.

1. Throttle carbon deposit is serious. Severe carbon deposition on the throttle will make the throttle opening inaccurate, leading to engine idling jitter. At this time, it is only necessary to clean the throttle, but if the engine still shakes after cleaning the throttle, it may be a problem with the throttle assembly. At this time, you need to go to the 4S shop for replacement. Remember to replace the original parts, the vehicle matching degree is higher.

2. Add inferior gasoline. Adding inferior gasoline will lead to insufficient combustion of air-fuel mixture in the cylinder. At this time, it is recommended to go to a regular gas station to refuel after using this box of gasoline. The fuel system must be cleaned in the 4S shop to ensure the health of the engine and make it work normally in the follow-up work.

3. Spark plug failure. Once the spark plug fails, it will not only cause engine idling jitter, but also be accompanied by symptoms such as power decline and fuel consumption increase. Please remember that once these complications occur, the original spark plug should be replaced in time.
