What is a potential reason for a sudden drop in fuel injector performance?

A sudden drop in fuel injector performance can often be attributed to blockage or contamination in the fuel line. When there are impurities, debris, or sediment present in the fuel line, it can obstruct the flow of fuel to the injectors. This blockage leads to insufficient fuel delivery, negatively impacting the injector's ability to atomize the fuel properly, which in turn can affect engine performance, fuel efficiency, and emissions.

Furthermore, contaminants can also interfere with the injector's components, potentially leading to malfunctions or clogged injector nozzles. Addressing fuel line blockages is crucial to restore optimal performance of the fuel injectors and ensure that the engine receives the right amount of fuel for efficient combustion.
