Fuel Injector Cleaning, Its A Joke!!!
I am looking at getting my injectors cleaned on My 1987 XF (obviously EFI), as I don't know if they have ever been cleaned by the previous owner(s) so I called around, mostly mobile mechanics (they come to you) and also actual mechanic workshops. The prices to get the injectors cleaned varied from $190.60 to $220, now heres the best part, that's not even taking the injectors out!, they said they run a carbon cleaning machine through it, how the hell does this clean it?, Im sure it would get some surfce carbon buildup off the injectors, but the carbon that would really be stuck on would not be touched. But to charge $196-$220 to do this, thats a joke. Has anyone had this done? Any improvement?
Can you clean them yourself? To take the injectors out is simple as, just take the plenum chamber inlet off, and fuel rail, could I just get them out, look at them with a magnifying glass and carefully srcape the carbon off with a fine screwdriver, and let them sit in a bucket of injector cleaner overnight?
Does anyone know a workshop around Melbourne that actually takes out the injectors and inspects them and cleans them out of the engine, not in it, I heard they use some machine they put them in for a thorough clean.
