What is the reason why BYD g3 can't run?

Hello, this phenomenon is generally caused by excessive carbon deposition in the engine or throttle. It is necessary to disassemble the intake pipe, manually clean the throttle valve to remove carbon deposits, so that the throttle valve can return to normal brightness, and then refresh the parameters of the driving computer, that is, ECU, through the computer to match the normal intake parameters, so as to eliminate abnormal conditions such as idling jitter, and the power improvement is also obvious. If my answer is helpful to you, please set it as the best answer.
