Need a little more info before we start throwing darts at ya. #1 is engine thats in your 4Runner. If its a 22R-E (4 cyl) then I would start looking at the auxiallary air valve that is mounted on the bottom of the intake manifold at the front. This valve and its hoses are what supply the extra airflow to give you the cold start high idle. IF its a V6 that you have...then hold out for more information!
