just thought id post up that been having trouble with above code on 02 sti and on advise from simon at jgm i have changed the nps on top of gearbox,it apears that when switch is faulty it can sometimes throw up missfire on 4 cel. i have drove car couple of times and cel has not come back so am praying to anyone that it has gone for good.(fingers crossed)some people dont mind driving there scooby with cel on but im not one of them,it makes me drive car with too much caution and spoils the idea of having a scooby wich is to have a bit of SENSIBLE fun-
clever guy that simon (JGM) cheers mate.
just when i thought i could stop spending money on it some b*****d has opened there peice of s**t on my door and dented it. nobends.

Is that a "P" code , P0304? If so thats misfire on cyl 4 detected. I'd check for plug, coil or injector fault
