Not necessarily. All cable throttles don't need to be matched, but electronic throttles need to be matched.
The cable throttle does not need to be matched. The cable throttle has one more component than the electronic one, that is, the idle motor. The electronic throttle has no idle motor. When the refueling door is at idle speed, the throttle damper of the cable is completely closed, and the air needed for idle speed is entered by the idle motor. The cable throttle has no self-adjusting ability, so it will be turned off completely without stepping on it. The computer always thinks that it is completely closed without stepping on the throttle.
the electronic throttle has no idle motor, and when it is in 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't be completely closed. If the throttle is dirty, carbon deposits occupy the passage of the throttle, and if the passage is narrow, the air will not enter smoothly, resulting in insufficient air intake, unstable idle speed and even inability to idle.
The throttle has a self-adjusting function. If carbon deposits are detected blocking some passages, then open the throttle baffle a little more when idling, that is, make the throttle opening a little larger, and the passages will be enlarged, so that enough air can enter. Self-adjustment ability is limited, and it is impossible to adjust it infinitely. When it is adjusted to the maximum, the phenomenon of unstable idle speed will appear, and many cars will light up fault lights to tell drivers that they need to repair the vehicles.
Extended information
The throttle valve is a controllable valve to control air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to become a combustible mixture, which will be burned to form work. It is connected to the air filter and the engine block, which is called the throat of the automobile engine.
four-stroke gasoline engines with throttles are generally like this. Throttle is one of the most important components in the engine system of EFI vehicle. Its upper part is the air filter grille, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of the car is flexible or not has a great relationship with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic. Whether the throttle should be removed and cleaned is also the focus of discussion among car owners.
