Chevrolet Silverado 2500 HD engine power issue requiring #4 injector replacement at 104,000 miles on Chevrolet Silverado 2500 HD

Some Chevrolet Silverado 2500 HD owners report experiencing reduced engine power, which may necessitate the replacement of the #4 injector around 104,000 miles. This issue can be triggered by various factors, including a faulty throttle body, MAF sensor, radiator problems, damaged wiring, or a malfunctioning PCM system. Owners often find that addressing reduced engine power requires a systematic approach, including decoding trouble codes and inspecting fuel system components, throttle, and sensors for potential issues. It's crucial to recognize that reduced engine power may not solely stem from a faulty throttle body or sensors, as other components could also be contributing factors. Additionally, recalls have been issued for 2010-2017 Chevy Silverado 2500/3500 models related to fuel level sensor failures, erratic speedometers, and multiple fuel injector failures, which may also play a role in these power issues.
