What is the reason why the sign 307 taxi can't afford to add the throttle in winter? Should the oil circuit and throttle be cleaned?

There are many reasons why vehicles can't afford to refuel. Weak high-pressure fire or some delay in ignition time will lead to incomplete combustion of mixed gas when accelerating to a certain extent, which will lead to the phenomenon of automobile acceleration. It may also be that the carbon deposition in the air intake, valve and combustion chamber increases, resulting in the mixture being too thin during acceleration, which leads to the inability to add oil; At the same time, we should also pay attention to check whether the air filter element is too dirty or the solenoid valve of the carbon canister can't be closed, which leads to too thick mixed gas during acceleration or oil collection, which leads to acceleration and car jam; Another possibility is that there is something wrong with the gasoline pump or the gasoline filter. When accelerating, the oil pressure can't keep up, which leads to truck phenomenon. It may also be caused by problems with various sensors. This kind of question needs a comprehensive investigation. I hope my answer will help you.
