Firstly,hello,Im new to Scoobynet.Ive got a MY99 UK Turbo with 67K on the clock with original clutch. I was on the motorway the other day,at about 85MPH i accelerated and found the boost to be surging,i accelerated further and it appeared to clear its throat,ive had a clutch go on my previous Impreza,but it didnt feel like that,im thinking boost solenoid or air flow meter,any feedback would be much appreciated??
