Against a firm concept among automotive mechanics that says "If it is working do not mess with it"...
...I am thinking about sending the injectors to get refreshed (after 160.000km). Has anyone done it before and would it be recommended?
My only doubt is that an injector cleaning company will always find at least ONE injector that had a problem so that you will not feel bad you have had them do the job.
Most of the people who have done it have max 1/6 injectors that was "dripping".
Regardless, I would like to know what are the signs in a car behavior that can point towards injector cleaning. Maybe looking at spark plugs? Type of deposits on the tips?
Any feedback is welcome.
Thanks!
Andre
