Main removal throttle valve

1 1 year, after Prima changed the timing belt, the cold car started idling unsteadily, and the flameout fault light was on, which could not be solved. After replacing the throttle assembly and spark plug, the car should be parked in the garage, and there will be basically no idling jitter caused by too low cold temperature. If this happens, on the one hand, it is considered that the fuel does not match the vehicle, and it is necessary to use American-made additives suitable for China's oil products, such as fuel additives according to the national standard of Guo Pu Six, to clean and improve combustion. These additives are directly mixed with fuel from gas stations in Europe and America for sale. There is no additive in domestic fuel, because the car was developed with European and American fuel, and now it uses China fuel, and the fuel quality is really different. On the other hand, consider whether it may be caused by carbon deposition, and the way to remove carbon deposition is to use detergent. Because other faults are not described, there is definitely no bad phenomenon after the hot car, so there is no fault in the accessories. This is not a big problem. The car is working normally and there is no problem. Most cold cars will have a little sense of fluctuation when they start, and good cars are not obvious, especially the cars in the garage will not feel obvious body jitter, and some will burn badly.
