What are the symptoms of mismatch after throttle cleaning?

The computer has a memory function and can adapt to the state before the throttle is cleaned. After cleaning, even if the throttle opening changes, as long as you copy it slightly, the computer will react directly. There are two kinds of signals. Common phenomena include idle speed rising, falling or getting higher. It is recommended to use a testing computer to match it. The above situation generally indicates that the throttle has not been cleaned for a long time. After the throttle is cleaned, if there is a mismatch, the following symptoms will appear. First, mismatch means that the minimum closing angle of the throttle valve itself returns to the standard value after the throttle valve is cleaned, but the original compensation value is stored in the computer, so it is necessary to clear the storage of the computer and return to the standard control data. Poor matching, poor throttle response and high idle speed. Second, after cleaning the throttle body, it is best to use a diagnostic computer for initialization settings. Many models can also manually match the throttle body to make the idle speed stable and fuel consumption the most economical. If there is no difference between idling now and before cleaning, the engine is working normally and there is no problem. Finally, because the computer has a memory function, it can adapt to the state before the throttle is cleaned. After cleaning, even if the throttle opening changes, the computer will respond directly. There are two kinds of signals, the common phenomenon is that the idle speed is high and low, so it is recommended to match the computer. The above situation generally indicates that the throttle has not been cleaned for a long time.
