ford 2004 f 150 heritage rough idle
My ford 2004 f 150 heritage just started to have a rough idle on the way to work. It only does this when you are stopped. It even shut off once at a red light tonight. I and not get any codes off of it. I had this check and it would not even connect to the turck to get the codes off. Not sure what to look for. It has 111000 on it and have never had a problem with it. Any help would be great!
