Why Won't the Car Move?

[McSara]

Here are the reasons why the car won't move: Throttle: The throttle is somewhat related to or interacts with the poor low-temperature fluidity of engine oil. Not cleaning the throttle for over 7,500 kilometers: If the throttle hasn't been cleaned for more than 7,500 kilometers, it becomes excessively dirty, leading to faults caused by excessive carbon deposits in the intake tract, fuel injectors, and intake valves. The uneven fuel quality and congested urban road conditions are all contributing factors to carbon deposit formation. During cold starts, the gasoline sprayed by the fuel injectors is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. Not cleaning the fuel system for over 40,000 kilometers: If the fuel system hasn't been cleaned for more than 40,000 kilometers, the fuel pump and fuel lines become excessively dirty.
