Thanks will check that out.

You should also check the idle speed control valve. It can be removed and carefully cleaned.

I have the same problem (rough idle when cold) and was told by a friend this was the problem. Apparently, its a common problem. I have not cleaned mine yet, but will getting to it in the next couple of weeks.
