@xecutionr (OP): Thank you VERY much for posting this thread last year! I appreciate it heavily.
My short story
I have been running through my own preventative maintenance checklist, and the IAC valve was on it.
However: I have never
known where the actual IAC valve was on the Zetec engine. Nor what it looked like (exactly).
Thanks to this thread: I now know! And especially thanks to my_beautious_ZX3
for uploading (high-quality!) photographs of it.
I will quite potentially upload a short video demonstrating the removal, and installation of the IAC valve now, and include a short picture tutorial.
But for now: I have only taken before, and after pictures of my own
IAC valve (cleaned with Throttle Body cleaner).
Here they are!!

Thanks again! The idle feels surprisingly different. Not substantially, but definitely noticeable.
