This is the last step to go to the 4S store to match. I think you should understand the principle. First of all, Nissan's CPU is very advanced, and its fuel injection quantity is based on the opening of the throttle. Therefore, the accumulated carbon on the throttle will change the flow and clearance of the throttle, and the processing value of CPU will also change. It's simple. You wash off all the carbon deposits on the accelerator at once, and the gap suddenly becomes larger. The CPU can't respond, so its data is still the data before you wash it, and the amount of oil it gives will increase with the increase of your gap and remain high. Therefore, don't wash it easily, and usually do maintenance such as gasoline additives. Of course, the matching of 4S shops is charged, and their method can only help you eliminate it by cooling the car. Don't be dissatisfied with yourself. Japanese cars are all like this. Is it too advanced?
