Clean the throttle. Why don't you take it down and clean it? Do I need a computer after cleaning?

To clean the throttle normally, it needs to be removed and cleaned. Some workers are lazy and spray cleaning agent directly into it. In fact, the back can't be cleaned, and the gap is not easy to clean. The cleaning agent residue is easy to be sucked into the cylinder. If the throttle is not very dirty, it generally does not need computer matching, and ECU will learn automatically. After a certain number of starts and stops, the throttle valve will work at the optimal opening.
