its very difficult to manually clean injectors since there are electrical
units and best cleaned with solution while they are working, (ie: on the car
and running) which is why fuel additives are by and far the best option for
i havent had any problems using fuel additives for this, there are many
different varieties out there, however i am in the UK so not sure what is
available to you in usa ???
wynns is ussually a good bet. and depending on the amount of fuel in your
tank when you add will determine the strength, (they will mostly all
reccomend adding to a full tank but i sometimes use half this amount.)
A service center will clean the injectors using a machine that flushes
detergent-laden fuel through the fuel rail under pressure with the engine
running. The vehicle's feed and return lines are disconnected at the rail and
(pump disabled) or connected (pump running) such that the engine operates
on the cleaning machine's supply alone. It does perform better than pour
in n' go methods.

Out of curiosity, what would one expect to pay for such a service?
I could replace all eight injectors in my vehicle in under an hour for
about $360 OEM---likely considerably cheaper after-market. I wonder what
the trade-off is by DIY replacement versus a service center's charge for
labor, use of the machine and tying up use of vehicle for up to a day.
(My injectors are fine at the moment. Just posing a question.)
In our shop we use BG 44K to clean the fuel delivery system, including the
injectors. Used properly, 44K will remove carbon build-up and the usual
"crud" that builds up in the injectors, and it's a great deal less expensive
than having a shop do the service and it works as well or better than
anything of the "flush" systems we've bought and now have sitting in the
cornerl. 44K is a professional strength additive so use it according the
insructions. you can buy it online at
