Bad soft brke fuel pump?
The rpm bounce is a clear indication of end of life. Were that my car I would have a pump on order. I'm saying the speed of the PUMP changing not the engine. They could be related but the pressure regulator should be able to supply constant pressure with minor hiccups from the pump
