Mine's a bit rough when it's cold at the moment, like the coldstart circuit isn't working.. Will look into when I get the time, but until then I tend to blip the revs upto 1500-2000 max while it's bad (normally only about 2 mins tops)..
Between then & fully warmed up it's max of about 3000-3500rpm, although I have been known to rag the daylights out of it when stone cold a couple of times - normally after an arguement with the mrs or something! :/
I feel more guilty about ragging the car when cold than the arguement that caused it usually though, is that bad?
