Rough idling is a sign that your automobile’s engine is not getting enough gasoline, and one reason why it might not be getting enough gas is that your fuel injectors are clogged. You will feel your vehicle vibrate as you sit at an idle, and you may hear the engine cutting in and out.

What does a faulty diesel injector sound like?

Engine knock results from the miss-timing of the combustion process between the injector firing and piston movement, resulting in a knocking sound from the engine. This symptom indicates that more components than just the injector are now involved. The common rail pump could be contributing to the fault.

What happens if you run a diesel with a bad injector?

  3. Smell of fuel.
  4. Dirty emissions.
  5. Increased fuel consumption and poor miles per gallon.

What are the signs of injector failure?

An abrupt loss of engine power is a somewhat obvious sign of a fuel injector failure. If the fuel injector is clogged, the fuel supply will be irregular too. When the fuel level fluctuates drastically, the high and low rpm’s will cause the engine to move in surges rather than slow and gradual movements.

What are the signs of dirty fuel injectors?

What is the average lifespan of fuel injectors?

“Fuel injectors have an atomizing nozzle that distributes fuel evenly for optimal combustion and efficiency.” Now, a vehicle will typically have one fuel injector per cylinder, with a lifespan of between 50,000 and 100,000 miles, or about 80,000 and 160,000 kilometers.
