engine management light

hi, just bought my first scooby, its a 95 wrx sti import, only had it a couple of days and now the engine management light comes on now and again and when it does it the revs jump up and down from around 500 to 1000, it only stays like this for a couple of minutes and then goes off, but when the light goes off the engine idles at 2000 revs, again for a couple of minutes the the light comes on and the revs drop again, i know nothing about imprezas, the last owner told me its running 320bhp and there is a racing gearbox and clutch fitted, the turbo still boost as it should, there is no smoke or any leaks anywhere, i dont have the funds just now to get it checked out and would appreciate any replies as to what might be the problem, thanks
