Which component’s function could be disrupted by an electrical short in a fuel metering system?

In a fuel metering system, fuel injectors play a critical role by precisely delivering the correct amount of fuel to the engine's combustion chambers based on the engine's demands. An electrical short can interrupt the signals or power supply to the fuel injectors, leading to improper fuel delivery. This might result in issues such as the engine running too rich or too lean, difficulty starting, or stalling.

The other components mentioned have separate functions that are not directly impacted by electrical issues in the same manner. The throttle body controls the air intake, the exhaust system manages the exhaust gases leaving the engine, and the transmission deals with the gear ratios for vehicle movement. While they are all essential to the overall functioning of the vehicle, they are not primarily affected by an electrical short in the same way that fuel injectors are.
