92 VG Injectors: Difference between black body and blue
For those who actually know:
I'd like to know the difference between the black-bodied and blue-bodied injectors. Yes... I know you should use all six of one or the other. I just want to know what the difference actually is- or more specifically: how much the difference is.
Thanks

another and related noob Q:
will the dot be the same regardless of manufacturer?
is it a "standard", and are the dots painted on, like with a paint pen, or are they put on during production, like a sticker would be(i know its not a sticker...)
and what does the dot mean? flow rate?
what do the different colors mean?

OK. Well, the basis for my question is that I had one original injector go bad (black body/blue dot) and replaced it with the 62005. I was trying to figure if that one injector would make a significant difference to fuel economy because of its type and flow charactoristics. I understand too that there could be an issue with one fresh injector with five others with 219K.
I have some other known issues to resolve that could be the problem (or part), and still some other diagnosis to do. Fuel economy coincidentally dropped about 4mpg after the swap... but the original injector was flaking- and then was down- long enough for other things to go wrong in the mean time so I don't know if I can blame the injector or not (or if it's one part of the problem). I need to replace the KS for one... even though it temporarily has a resistor in its place for now. Replaced O2 with TKN, still need powervalve actuator and maybe a CTS. Need to check other things.
