What's the matter with Jing Cheng's car blocking the throttle and not turning off the engine?

Hello, this situation is caused by air leakage in some places. Try to get some foam water to see where the air leaks. For example, if the sealing ring of the oil nozzle is broken, you can check the air leakage of the intake branch pipe. Just deal with it. If you can't solve it yourself, go to a repair shop or a 4S shop. I hope my answer is helpful to you. Have a nice ride!
