Just a little update, car hasn't been running properly lately, lumpy idle, hesitation at 2500rpm and crap fuel consumption
Simon (JGM) came round yesterday and it seems my lambda sensor has packed up, Simon did have a spare sensor but unfortunately it was the wrong one
For a laugh i phoned Subaru and they wanted £242.45 , on the advice of Simon i got in contact with Just Lambda and they are sending me one for the grand total of £69 inc delivery
