05 Ford Escape Idle Air Control Valve noise
My wife just bought a 05 Ford Escape a few months ago. It has a 3.0 L V6 engine in it. It has been very cold here in PA. Every time she starts her Escape when it is very cold out, the IACV seems to be sticking and makes a whistling noise for a few seconds after she starts the engine. At least that is what the Ford service tech tells me that is making the noise. And he tells me that the noise it is making is normal. That is hard to believe. I just did a goggle search on this subject and only found a few worthless articles on this problem. Can someone with some engine experience tell me if this is normal?
