Is it normal for Baojun 630 to open the key without starting to step on the accelerator?

This fault phenomenon is closely related to carbon deposition, so it is very important to check the carbon deposition of electronic throttle body. Excessive carbon deposition in electronic throttle body will lead to unstable idle speed, difficult starting, jamming during driving or flameout during driving. If there is carbon deposit, clean up the carbon deposit first, and then observe it in trial operation. Under normal circumstances, the opening of the vehicle throttle body should be 1~2 degrees. If the opening reaches more than 3 degrees, it will affect the normal use of the vehicle. For vehicles driving in urban areas for a long time, it is recommended to clean the electronic throttle body every 15000 km and run expressway once a month. Many vehicle failures are caused by carbon deposition.
