Cheers guys, I'll give all those a try. Kev, think we already discussed the ECU in another thread, but its the 2009 part number that ends in -11.
I'll have a fiddle with the idle speed at the weekend and see if that sorts it. Not a major problem though, just a little annoying. It never happens at a decent speed, only when trickling.
Good excuse for me to start modding a little I guess
