Yes, worn-out o r clogged fuel injectors can cause poor fuel economy. The fuel injectors are responsible for delivering fuel to the engine in a fine mist, allowing for efficient combustion. If they become clogged o r malfunction, they can deliver too much fuel o r an improper mixture, leading to inefficient fuel consumption.

Symptoms of Worn Injectors: You may notice poor acceleration, engine misfires, rough idling, o r black smoke from the exhaust.
Clogged Injectors: Clogged injectors can cause uneven fuel delivery, which results in excess fuel consumption and reduced engine performance.
Solution:

Injector Cleaning: Have the fuel injectors cleaned using an injector cleaning solution o r a professional service.
Injector Replacement: If cleaning doesn’t resolve the issue, you may need to replace the fuel injectors.
