I got my injectors from nissan... they gave me pink ones. I've had the #5 replaced a few months back, but am not getting the rest done. Will it be alright?
Also, I have the 5 injectors, 2 sets of seals, and 2 gaskets, going to get throttle body/carburator cleaner to clean the throttle body while I'm at it, but is there anything else I should do when it's open?

 

uh oh. another injector color issue.

they say now that they have done away with the black dot/blue dot thing. now they have a "universal" one. the "#5" is irrelevant, btw. and now the color is, too! hah! and i just got accustomed to the original way!

this may be what you have.
