SlowSWP2.5 Posted June 10, 2016 Share Posted June 10, 2016 I own a 2007 legacy 2.5i and I have a check engine light on and my idle is rough. It idles at just above 0 at idle and almost stalls. In reverse it does stall. So I brought it to a shop and they pulled the code. PO506 idle control system low. They said I need to replace the IAC sensor, but I can't find the part anywhere online or a write up about it. I researched this and there is no info on how to replace it for my year legacy. I did read that this year model doesn't have an IAC sensor which I don't know if it is true or not. Any help is appreciated. Link to comment Share on other sites More sharing options...
