What is injector tick?

So the ticking is from a moving part in the injector like an actuator opening to release the fuel during its duty cycle.

What are the signs of a failing fuel injector?

What is the lifespan of a fuel injector?

"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.

What are signs of a clogged fuel injector?

Why is there a ticking noise when I accelerate?

With the engine, the tapping noise is either lack of oil lubrication in the top of the motor (or loose valve train hardware like lifters) or due to engine knocking (small misfires). In the axle area, this type of noise can be caused by damaged CV joints, or even a brake rotor that is warped.

Is it better to clean or replace fuel injectors?

Fuel injectors should be cleaned at least once every 36 months, or 45,000 miles. Replacing weak or worn-out engine parts without improving performance is not a good idea in general.
