What is the matching method of Dongfeng Nissan converse throttle?

08 Liwei throttle matching method: It is recommended to match the electronic throttle of 4S, because it is necessary to connect the driving computer to adjust the throttle size and waiting speed. Matching of automobile throttle: Whether the automobile accelerates flexibly has a great relationship with the dirt on the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and powerful. Under normal circumstances, there is no need to match the throttle, because the throttle is closed at idle speed and does not participate in air intake, but the idle speed depends on the idle valve. If it is an electronic throttle, it generally needs to be re-matched (also called throttle initialization). Because the opening of throttle valve is adjusted by computer, it has memory function. Due to the blockage of sludge in the past, the computer will automatically adjust the opening of the throttle valve to keep the intake air in a normal state. But there is no sludge blockage after cleaning. If the throttle valve still keeps the original opening, the intake air will be too large, the engine will shake and accelerate when it starts, and the engine fault light may light up.
