I have a 2010 Ford Expedition 5.4 3v, I have had it at several different shops and they can't see to find the issue. My idle when at a stop drops down low under 600 rpm unless I put it in neutral. I heard about drilling a small hole in the throttle plate since we don't have an IAC. I have already replaced the the throttle body with a new Ford one. Would drilling the throttle plate raise the idle?
