Hello and welcome to JustAnswer!

It sounds as if the engine is either going into limp in or you have an injector related issue. If an injector is over fueling that would explain it running rough and RPM's being higher than intended.

Do you get any abnormal smoke from the tailpipe?
Are the symptoms the same now as before replacing the injector?
What was the reason for replacing it?

Hello. Sorry for the late answer, I was overcharged by the work. No abnormal smoke. The symptoms didn't evoluate after injector replacement. (I did change the injectors beacuse it seems there was a cylinder not igniting (unplug - replug the connector of the 4th cyl. with no change...). It looks more electronical than mechanical, so far.
