Hey guys, got my series 2 rs-four stag about 2 months ago, loving it i must say! Only thing i don't love is the fuel consumption, i have just done 330km to just under a full tank and i spent 90% of that time off boost.
Alot of people talk about it being the O2 Sensor, so i pulled mine out to check the condition of it, to me it seems in pretty good nick (car has done a touch over 100k's).
another thing is the guy i bought it from lived way out in the country side, and i live in the city, so an ecu reset is probably a good idea, but after 2 months i would have thought the car would have adjusted by now.
cheers matt
