What can a clogged fuel injector cause?

A clogged fuel injector can lead to reduced engine power and efficiency because it disrupts the proper flow of fuel into the combustion chamber. Fuel injectors are designed to deliver a precise amount of fuel at the right time to ensure optimal combustion. When the injectors are clogged, they may restrict fuel flow or cause uneven distribution of fuel, which results in incomplete combustion. This not only diminishes the engine's performance, leading to sluggish acceleration and a decrease in overall power output, but also affects fuel efficiency as the engine may compensate by running richer or misfiring. In this way, a clogged injector negatively impacts the engine's ability to perform at its best, supporting the idea that reduced engine power and efficiency are key results of this issue.
