Why can't Tiggo 3 start and how to fix it?

Hello, this car is like this. When the 1 gear is shifted to the second gear, the VIS acceleration short air inlet will not be opened until 1500 rpm or more. More importantly, the VIS actuation system is not a solenoid valve based on electrical signals, but is connected to the negative pressure vacuum of the throttle valve and pneumatically driven by the negative pressure vacuum generated by the intake of the throttle valve. The action system will seriously lag behind the throttle, which is the throttle! This is why meat accelerates. Another fatal injury of 4G 16DVVT engine is that the throttle will suddenly become soft or slow, and sometimes it needs to be released and then stepped on. Very casual, no rules to follow. This is a fragile wound on the tiger. This fatal wound is the vacuum accumulator! There is no valve control between this thing and the intake of the engine, which is an incredible normally open state. There is only one one-way valve to ensure that it becomes a brave dog and can only go in and out. This amazing design makes your throttle and engine loaded with this extra super vacuum booster pump, and the air that enters the engine for combustion and work is randomly sucked into the vacuum accumulator, so that every time you step on the throttle, the air from the throttle can't enter the engine at all. So the acceleration is weak and sluggish. Climbing stall.
