Fuel Injectors

[Brett N Augsburger <augsbbn@eng.auburn.edu>]

I seem to have been having some problems with my fuel injectors for some
time know. At one point the injectors were so bad the car would barely run
and I had a local shop clean them for me. They said the patterns looked
terrible but were not too bad after they cleaned them. That was over a
year ago. I always run Chevron supreme and use a bottle of Techron before
each oil change. The car runs OK now but not like I would expect it to,
considering it has a new head, and everything is in perfect running order
as far as I can tell. My question is, should I replace the FI's or have
them professionally cleaned. The car has 150k miles on it. New injectors
would run me about $220, cleaning about $130. Any suggestions?
