How to clean the throttle of Honda Accord?

1. Because there will be impurities in the intake process, these impurities will accumulate at the throttle for a long time, and the carbon deposition will increase after a long time. When the throttle reciprocates, it will be resisted for a long time, so the engine computer will adjust the position of the throttle. In other words, the position of carbon deposition is regarded as the valve body, which means that the throttle valve is closed to the position of carbon deposition rather than completely closed. 2. After cleaning the intake valve of the vehicle, rotate the disc according to the original molding action, which is equivalent to not being in place, but the carbon deposit has been cleaned up. So the air intake will be a little more than usual. Resulting in high idle speed. In this case, it is necessary to carry out computer programming. If there is no engine, the computer will take a long time to adjust and recover.
