Then I got to thinking... not much coolant came out when I disconnected the lines to swap iacv's. Normally those lines should flow a lot of coolant if disconnected. On that engine I just ended up installing an iacv delete plate since I didn't feel like trying to clear the lines. That fixed my idle issues... aside from cold starts...
Very interesting. If I remember correctly, when I disconnected the lines from the IACV there was not a lot of fluid either. Things are making some sense. I have an IR thermometer somewhere. That is also a good test.
