Hello everyone.

I am looking for new fuel injectors to replace my incredibly worn stock original ones. With 211k miles on them they can't be in very good shape.

I have posted on this before, but economic times being what they have been I am finally able to do this project and am looking to finalize my choices.

The stock injectors in my Ranger are 14# single hole injectors. From a poster some time ago I had looked at 14# injectors from a 2000 Ford Contour. These have 4 holes rather than my single hole ones. Seems like an improvement to me with better spray/atomization.

If anyone has any other options I am all ears. Different number of holes, poundage, fuel pressure, etc.

Also, I have heard about "flow matched" injectors. I assume these have a tighter tolerance so that each one is equal (or at least closer) to the rest. I'm sure they are more expensive and worth the extra money.

What companies would you suggest for buying these? Any to stay away from?

Also, I have heard that I should change the O2 sensors at the same time to help the computer learn the new set-up. Any truth to that?

And lastly, (yeah I know I'm always full of questions today), is there any "re-tuning" of the computer that needs to be done or that could be done (in addition) to help improve my FE.

Thanks everyone.
