fast idle

I noticed this morning that my truck no longer has the fast idle on cold mornings. Where should I start looking?

How cold? On a moderately cold day the high idle may not kick in. Auto or bolt action?

Make sure your air temp. sensor is hooked up. It is the thing inn your air box. I had mine unhooked due to putting 6637 air filter on and mine wouldn't idle up until i put it back on. Just a thought.
