Matt, I really doubt you're having ANY fuel injector problems and I even
more strongly doubt they need cleaning. Today's injectors with todays
fuels that ALL contain fuel injector cleaners keep them pretty darned
clean. They just don't wear out this quickly, 110,000 miles is not a
lot of miles at all. Mine have 160K miles on them and I know plenty
with over 220K miles on them. Just trying to save you a bit of $$$ and
time.

Interesting note. There are at least two different types of injector
designs out there. The older ones use fairly high current to keep the
injector valve open. Others use a higher current pulse to open the
injector and a lower current to keep them open. That type uses a much
finer coil and is more suceptable to overheating and shorting out.
