My 1997 subaru impreza is revving like crazy on start up, accelerating and then losing power when drive without me touching accelerator?

First, make sure your airfilter is not plugged. If it is, the engine is compensating for the lack of air intake. If not, consider replacing the Idle Control Valve. Inquire with an auto parts dealer (store) for this part.
Please let me know if you need further assistance.

What does the diagnostic code P2181 mean on a Subaru Impreza WRX?

this is a coolant performance code. Usuallly sets this code if the connector was left unhooked to the coolant sensor or the thremostat is stuck open. By any chance do you have a gauge that seems to be on the cold side ??

I would start with the fuel filter. If the flow is restricted it drops pressure needed at higher RPM's. Then check Catalitic converter. May have restricted the exhaust flow. Always good to start with the basics. Good luck and have a great day.
