Impreza loss of power

Hi

im new to the site, have 99uk impreza turbo (classic shape) no engine mods to the car

all of sudden car seems to have lost power or boost, the turbo (if its running) isnt coming in with the same whirring noise and force and torque as it was... the car only has 61k on it so it shouldnt have been the turbo?it still feels quick(ish) but its having to be revved out too much to get it to feel close to be quick....

where do i start fault finding and what are my potential problems???

thanks a lot

Hi.

Is the tickover erratic? Is the engine/CEL light on?

I don't think it's likely. I reckon you would get a erratic idle if it was the MAF.

You could try a ecu reset.
