It has started on occasions, when slowing down for roundabouts and juctions etc the revs wont come down below 2k, and on idle it varys between sitting at 1.5k or flutuating between 900-1200k....

all idea's have led to ICV in my book, but not too sure now

It doesn't do it all the time either tho, so was thinkin i was catchin the problem early, but now who knows! lol
