QQ308 automatic gear failure! Ask the master to answer!

Focus on checking the throttle valve body. It is possible that the valve inside the throttle is loose or stuck. When stepping on the accelerator pedal, the cable is used to control the flaps. Whether it is loose, loose or stuck, the throttle response will be biased, or check the throttle position sensor. Because of the sensor problem, the signal will be abnormal, which will also lead to signal problems and failures. Check the idle motor and idle control valve, because the problems of idle motor and control valve will lead to abnormal idle intake, especially the concentration of mixed gas, which will lead to abnormal combustion. And check whether the accelerator cable is stuck. If it gets stuck, it will also cause the deviation between the throttle and the throttle opening and closing. Secondly, check whether there is any aging virtual connection between the throttle harness and the plug. I suggest you ask the 4s shop to pour the accelerator for you first. The problem is solved, and it is the throttle itself. It is suggested that it is best to check the fuel injector and wiring harness and check the pulse of the fuel injector. If there is no problem in the above inspection, it is recommended to check the engine computer and wiring harness.
