Just bought a 95 wrx. It is completely standard.
Its jerking under even just a slight acceleration at around 2.5k revs and above or if you put your foot down slightly to much(any more than about 10% throttle). Its like all power drops out and back in and there is no increase acceleration. Also it is basically un-able to climb hills.

Is it fuel related eg fuel pump or something. This is my first suburu.
