Fuel injectors can fail due to a variety of reasons, such as clogging, leaks, or electrical issues. If you notice symptoms like rough idling, decreased fuel efficiency, engine misfires, or a loss of power, it may be time to replace your fuel injectors. It’s best to consult with a mechanic to diagnose the problem and determine if injector replacement is necessary.

Fuel injectors can last for many years, but their lifespan can be affected by factors like poor fuel quality, excessive heat, and harsh driving conditions. On average, fuel injectors can last between 50,000 and 100,000 miles before they need to be replaced. Regular maintenance, such as fuel system cleaning, can help extend their lifespan.

Some common signs of a failing fuel injector include rough idling, decreased fuel efficiency, engine misfires, and a loss of power. You may also notice a strong fuel smell or black smoke coming from the exhaust. If you experience any of these symptoms, it’s important to have your vehicle inspected by a mechanic to determine the cause of the problem.
