If you have never gotten the injectors serviced, it might be worth it. Every time, I got my Civic's injectors cleaned, the car became more responsive. My car has done 260,000km. I have done injector cleaning thrice.
First time with injector cleaner that is poured in the tank.
Second time with Liquimoly injector cleaning service.
Third time from Honda Fort. they physically dismantled injectors and cleaned them. They did not have proper equipment for testing injectors and cleaning them, so they did it manually.
Best results were obtained with the third method. I also intend to go for injector cleaning again. This time I will try magic motors.
Results are smoother idling, more responsive throttle, fuel consumption might improve depending on how badly clogged the injectors are. It is definitely worth it.
