Has it always done this (as long as you've had it) or did it just come on suddenly?

There are may things that can cause this, with more info we can narrow it down faster instead of throwing lots of expensive parts at it to test it.
Dave, it has done this since I have had it. Cold weather or warm and it does it even once that car is up to temp.
