Does a faulty fuel injector cause engine noise?

[PatrickLynn]

Symptoms of a faulty fuel injector include engine noise. If the fuel injector is malfunctioning and fails to operate normally, engine symptoms may include severe carbon buildup in the cylinders, accelerated wear of the cylinder liners and piston rings, resulting in unstable idling, increased fuel consumption, poor acceleration, difficulty starting, engine noise, and excessive vehicle emissions. In severe cases, it may even damage the engine. Below are details regarding fuel injector cleaning: Fuel injector cleaning interval: Generally, most recommendations suggest cleaning every 20,000 to 30,000 kilometers. For vehicles in good condition with high-quality fuel, this interval can be extended to 40,000 to 60,000 kilometers. Hazards of long-term neglect of fuel injector cleaning: If fuel injectors are not cleaned for an extended period, clogging becomes more severe, leading to poor fuel injection, improper spray angle and atomization, and suboptimal engine performance during idling, acceleration, or full-load conditions. This results in reduced engine power and increased fuel consumption.
