I think my 2004 Mercury Mountaineer needs a new IAC valve. Sometimes it turns of when I put it into reverse. It also has a Service Engine Soon Light that is on and giving me the code P0506. I want to replace it on my own with no help from a mechanic. My only problem is I cannot find the IAC valve.
have the same problem?
