Hello, the idle speed of 20 15 Camry 2.0 leading version is high after cleaning the throttle. Do I have to have a computer? Can I match it manually? thank you

Camry, if you wash the throttle, you can try turning off the power. It means that after you wash the accelerator, the idle speed is high. After you approve the fire, take the negative electrode of the battery apart, wait for dozens of seconds, and then connect it. Toyota's car basically needs power-off matching after washing the throttle, so as to restore the original data. Also, for example, when the power supply is cut off, the idle speed will be very low. If you want to turn off the engine, you need to clean the throttle. Some cars don't wash the throttle for a long time, and then hit someone to turn off the engine after the power is cut off. Idle speed is very low because it will restore the original data after you cut off the power supply. Your throttle is already dirty, so there will be a low idle speed. So you should be able to cut off the power. You don't need a computer to match it Or it can learn by itself after a period of time.
