mine has done the same thing, and the consult thing says primary ignition error or something, mechanic screwed me over and making long story short, check ya coils.
i did a search on here, and everyone with these warning lights in a r34 fixed it by replacing coilpacks
i have spitfires on the way, so if u havent sollved it by then, ill let ya know how i go.
however mines gone one further and actually sounds like a WRX on steroids lol (( i think from a cylinder not firing or sometihng
