Mixing old (cleaned) injectors with a new one?

[adams172]

Just had my injectors cleaned to cure a misfire, and one is apparently faulty and cannot be repaired - so I'm wondering, will it be OK to use the old ultrasonically cleaned and fully tested ones with a brand new one, or is this likely to cause issues?
I'm on a budget here, but don't want to cause damage at the same time!

I used Injectortune and they have advised that they have the correct matching part in stock if I want it.

Thanks in advance
Adam

Assuming the flow rate is the same (or very close) age doesn't matter really.
