An automobile engine runs hotter than usual in the stop-go traffic. This extreme heat vaporizes the fuel in carburetor and fuel pump.

Vapor lock is caused by heat. Excessive heat from the engine, exhaust system, and/or outside temperature can cause the fuel to vaporize in the lines. Some winter fuel blends and high altitude can lower the boiling point of the fuel. This can also contribute to vapor lock.How do you dry out a wet engine?

An improperly sealing fuel cap may cause an evap system leak, which will set off the Check Engine Light when the the computer detects the leak.Does ethanol cause vapor lock?
The vapor pressure of Ethanol is much lower than the vapor pressure of Gasoline. Therefore a critical vapor liquid ratio, which can cause vapor lock, will be reached at lower temperatures with Gasoline-Ethanol blends than with regular Gasoline.What causes vapor?
When liquid water is evaporated to form water vapor, heat is absorbed. This helps to cool the surface of the Earth. This "latent heat of condensation" is released again when the water vapor condenses to form cloud water.Can you clean fuel injectors?
