Please help!! I have a 2002 Expedition with 116,000 miles. It will occassionally idle up around 2500 to 3000 rpm while driving or in park. I changed the IAC and it seemed to help for a week, but now it is back. Sometimes you can push down on the gas pedal and it will drop down to normal. Has anyone experienced this? and if so where do I start.
Thanks Todd
