Fuel Injector/Carbon Cleaner

[james accordino]

I did replace the seals along with the injectors and
they come out easily.  VERY tough when the seals are
old and hard.  Maybe you've been lucky or it's that
mines a turbo or the gas by me sucks.  After x
thousands miles, it'll start running kind of crappy
and the mileage starts to go down alittle.  Injector
cleaner usually helps in my case.  Yeah, I used to do
that all the time, but in this case, I didn't feel
like opening either of these motors, so I just kept
chemically treating the carbon.  The scotchbrite
wheels work real nice on combustion chambers without
any damage to the aluminum.
