This is my first post, and I just want to say thank you -thank you to this forum. It's awesome.
My car refused to idle yesterday. It would run only so long as the throttle pedal was pressed; as soon as I let up = stall.
Then, I looked in my Haynes manual for ideas. No frickin' help there whatsoever. Next step: this forum (the archives actually). I found info about the idle air control valve, it made sense, I replaced it today, and voila! Problem solved.
Anyway, the Ford/Motorcraft Part # reads:
CX-1881

Hope this helps someone else. Thanks again!
