[Red maple is like fire] LaVida cleaning throttle operation
TrumanHazlitt 
7 The throttle is a controllable valve that controls the entry of air into the engine. After entering the intake pipe, the gas will be mixed with gasoline into a combustible mixture, thus burning to form work. It is connected with the air filter and the engine cylinder block, and is called the throat of the automobile engine.
Before Sanbao, the 4S shop master suggested that it was time to clean the throttle, and I would listen carefully to the advice given by the maintenance master every time. Because they have received formal training and guidance from manufacturers, they should be the most professional in the maintenance of Volkswagen. However, according to my personal situation and the environment of using the car, I generally choose to extend one or two times of maintenance to do. Between fingers, Xiaolang should also be guaranteed. Recently, after reading the course stickers for cleaning throttle valves in the forum, I intend to clean the throttle by myself before the four guarantees. Although there is nothing unusual about the car, I decided to wash it by myself, which is healthier. You can also judge whether it is time to clean the throttle by feeling, such as unstable idle speed, jitter, easy flameout, weak acceleration. Although this is the first time to clean the throttle, but still summed up some experience, the following to share with you, of course, the shortcomings are also asked to correct, I can modify in time, so as not to mislead more cyclists.
How to clean the throttle:
1. It is free of disassembly and washing. Remove the upper cover of the engine to expose the throttle car key is electrified but do not start with something against the throttle, spray the throttle cleaning agent on the cloth to wipe the throttle flip plate and the inner wall, this method of cleaning is not thorough can be used in the case of less carbon accumulation in the throttle.
2. On the basis of the first method, remove the four screws that fix the throttle without pulling out the wire harness, pick up the throttle and spray the cleaning agent first and then wipe it, spread a piece of cloth at the bottom of the spray cleaning agent or catch it with a container, if you just spray it first and then wipe it, you don’t have to worry about the spray cleaning agent flowing into the engine room, because the cleaning agent used after spraying first is small and the cleaning agent itself is easy to volatilize. I think this method is feasible and can effectively clean the front and back of the throttle, but the disadvantage is that the wire harness restraint operation is not very convenient. If you do not unplug the wire harness, there is no need to match, then the two methods do not need to match after cleaning.
3. Remove the screw and pull out the wire harness, remove the throttle completely, spray it with cleaning agent and finally clean it thoroughly.

Tools used to clean the throttle meter corner wrench (including T10–T50 a total of 9 pieces of throttle used T30) throttle cleaner a bottle of soft hair discarded toothbrush (originally intended to clean difficult to clean the results of carbon deposition is not useful) the Phillips screwdriver had better go with a long one.
Use a Phillips screwdriver to remove the nine screws from the upper cover of the engine. The screws do not need to be completely unscrewed off from the lower cover, and then move the upper cover to one side without affecting the throttle.
After removing the engine cover plate, the exposed throttle can be seen from the gap between the overturned plate.
If the car key is not powered on, use a screwdriver against the throttle to fully open the throttle to further check the reverse area of the throttle.
Press the throttle against the throttle through the screwdriver in the car, and the throttle is fully open. at this time, you will hear the beep of the machine, which is dirtier, and a simple scrub is far from enough.
Remove the four screws on the fixed throttle, then use the T30m inner angle wrench to loosen the screw with a wrench and then remove the screw by hand. The advantage of this is to prevent the screw from accidentally falling into the cabin. If there is a magnetic force in front of your wrench, so much the better.
Arrange the screws in order, and finally install them in place.
At close range, the reverse side is already very dirty, so it seems that it is a good time to clean it.
Unplug the wire harness, there is a stop above the wire harness plug, press and gently pull out to separate.
Remove the throttle completely and plug the exposed intake manifold with a prepared towel to prevent it from falling or flying in.
The throttle that has been completely removed has green paint on both sides of the factory, which also proves that this is the first time that Xiaolang has cleaned the throttle. I will wash the throttle for you for the first time and make sure it is clean. Only after I serve you today can you serve me better.
Spread the prepared newspaper on the floor and catch the detergent to protect the environment. Hold the throttle in one hand and the detergent in the other, spray the opening of the throttle downward or sideways to clean the throttle, do not spray the opening toward the face to prevent the cleaner from splashing on the face or body.
After a burst of spray, the black carbon deposits are washed down, and then wipe them off with a complimentary mask (non-woven cloth). In the process of careful re-cleaning, I didn’t dare to move the board.
There is also a 5 degree on the front. Is this the opening degree of the idle speed reference?

Like many riders, the most worry about cleaning the throttle is matching. I referred to the 30-second matching method mentioned by the riders. The keys in the car are electrified but not activated, electrified for at least 30 seconds, so that the driving computer can complete the self-test and match naturally. Then after restarting the vehicle, watch the dashboard water temperature rise and idle speed drop. The match proved to be a success, and then I drove away to further match the throttle.
This is almost the end of the post. Here are two tips for motorists who want to clean the throttle:
1. In the selection and purchase of throttle cleaner, it is best to choose the cleaner with lubrication effect.
2. The detergent smells pungent and corrosive, so it is best to wear a mask and gloves.
