Did Emgrand wash the accelerator 20? 35 Idle speed is unstable.

After cleaning the throttle, the most direct manifestation of not re-matching is that the idle speed will be high and the idle speed will automatically increase. Some engines will increase the speed to 1500 r/min or even higher, with high fuel consumption and excessive emissions. The exhaust pipe will emit black smoke when accelerating.

After cleaning the throttle valve, the engines of the United States and Japan do not need to be matched again, and only need to 1rain to disconnect the negative electrode of the battery, so that the control unit loses its remaining memory and can return to normal.

Mazda 6 electronic throttle reset. Disconnect the negative electrode of the battery for 5s, and then reassemble it. Turn the ignition switch to the 0N position, press the accelerator pedal for 5 seconds, and then release it. Turn off the ignition switch, then restart it, and check whether the engine speed can drop normally after releasing the accelerator pedal, that is, complete the electronic accelerator setting.
