Do I need to match the throttle after cleaning?

Not necessarily, all cable chokes do not need to be matched, but electronic chokes need to be matched.

Cable throttles do not need to be matched. Cable throttle has one more component than electronic throttle, that is, idle motor. The electronic throttle has no idle motor. When the refueling door is at idle speed, the throttle baffle of the cable is completely closed, and the air required for idle speed is entered by the idle motor. The cable throttle has no self-adjusting ability, so it will completely turn off without stepping on it. The computer always thought it was all off without stepping on the gas pedal.

The electronic throttle has no idle motor. In the idle state without stepping on the accelerator, the throttle baffle also has a small opening to let the air enter the idle state, which means it can never be completely closed. If the throttle is not clean, carbon deposits will occupy the passage of the throttle. If the passage is narrow, air cannot enter smoothly, resulting in insufficient air intake, unstable idle speed and even inability to idle.

The throttle has an automatic adjustment function. If it is detected that some channels are blocked by carbon deposits, then when idling, open the throttle baffle a little more, that is, open the throttle a little more, and the channels will become larger, so that enough air can enter. Self-regulation ability is limited, and it is impossible to adjust indefinitely. When it is set to the maximum, the idle speed will be unstable, and many cars will light up the fault light to tell the driver that the vehicle needs to be repaired.

Extended data

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

Throttle four-stroke gasoline engines are generally like this. Throttle is one of the most important components in EFI automobile engine system. Its upper part is the air cleaner grille, and the lower part is the engine body, which is the throat of the automobile engine. Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and powerful. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.
