Hello everyone, I just found this site and s far I love it, I do have a problem my wife drives a 2000 expedition with a 5.4 it has 177,000 miles and still runs strong (of course it does it is a FORD) it now has developed a problem when it relly cold it does not want to run when you come to a traffic light unless you shift into neutral it drives fine on the road, i did replace the idle air control valve and it still does it, like I said it only does it when it is cold I need help.
