-I am trying some fuel injector cleaner now and will take to another dealer tomorrow. I just had thought that the dealer could diagnose the problem with more accuracy, instead of attempting fix after fix and not trying inexpensive stuff first. I have no problem with the injector replacement if it works(700.00) but it's a lot of money if it doesn't work.
-I just changed fuel filter and I saw no metal flakes anywhere. Thanks for the help
