I had asked about yellow fuel injectors a few weeks ago, and no one seemed to be able to tell me exactly what they were.
I bought some of the popular orange fuel injectors, and when I compared the two, they have the same part # molded on the side.
My car has 223k miles on it. At idle it doesn't run as smooth as I think it could. If one or more injectors have too much wear, or if they may be starting to clog, do you think it would be a good idea to replace the injectors, one at a time, with the orange injectors, and see if there is any difference.
Can anyone tell me why I shouldn't do this?
Thanks for any help.

All of the injectors are calibrated together.

You should change all of them at once.
