Cheng Jing 1.8 10 How to match the replacement throttle?

At present, the throttle has no throttle line, and it is all electronic throttle, and the idle opening of the throttle is controlled by computer. When the throttle valve is used for a certain kilometer, there will be dust such as carbon deposition on the throttle valve. At this point, the throttle opening is still controlled by the computer-increase the throttle opening and maintain normal idle operation. At this time, if the throttle is cleaned, the throttle opening will become larger, making the idle speed unstable or high. At this time, you need a matching throttle. The matching methods of various cars are different, so it is best to go to 4S shop and match with special instruments.
