Nobody believes in just running good Injector cleaner through their fuel systems a few times a year. Granted the OP is most likely correct and his are fine. I just dont see the sence in pulling injectors that are working.
Then you go get a set out of a junkyard and send them somewhere to be cleaned.
Those really can be cleaned yourself and some form users show how it can be done.
Oh well to each ones own. Whatever works for the users.
I just run some good fuel injector cleaner through a fuel times a year and I haven't had the need to change an injector yet in 30 years. I am not this lucky so it must actually keep them clean.
