I pulled the injectors from my DJ-code engine to replace them with a set
from an MV-code 2.1L.  The original injectors were yellow, while the MV-code
injectors are black.  Is there a significance to this color?  Both engines
are from 1989.

I'm asking because now, although smoother, I feel there's a little less
power when accelerating from 65 to 80 mph.  I thought maybe the black
injectors had lower flow rates.
