How to disassemble and match the throttle of Toyota Highlander?

Removal method of Highlander throttle: Highlander throttle is generally fixed with four screws, the upper two screws are easier to remove, and the lower screws are somewhat awkward. We suggest that the following two hard-to-remove screws should be removed first, so as to avoid that the lower screws cannot be removed because the upper screws have been removed and are not fixed, and the throttle shakes. After the four screws of Highlander throttle are removed, the throttle can be removed, and the exposed pipeline is the air inlet. Highlander throttle matching method: 1. Turn the key to the power gear first, and never start the car, that is, turn it off. 2. After standing for about 15 seconds, quickly step on the accelerator pedal to the end, be sure to step on it quickly, hold on for 15 seconds, and then quickly lift the pedal. 3. Then close the key door, take out the key and let it stand for about 15 seconds. 4. Start the car normally and match it. Throttle is a controllable valve, which is used to control air to enter the engine. After entering the intake pipe, it is mixed with gasoline (different models of cars have different design mixing parts) to become combustible mixture, which participates in combustion and does work. Four-stroke gasoline engines are generally like this. Throttle is the most important component in EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle.
