those of you who had hanging idle and high idle issue, and/or code P1506, you ain't gonna believe what it was!
I had these issue with my car for a while - and i replaced IAC, and cleaning IAC, cussing, resetting PCM several times, and none worked. I continued to have an issue.
It turned out that i had a leaking passenger side PCV valve! took it off, cleaned it, and install it back in, all my probrem is gone! she is now idleing exactry as it was intended!
So if you have above issue, you guys might want to check your PCV valve. groumet isn't the best on them!!
