When I removed my IAC to clean it I noticed that it was a Ford casting. Needless to say Cleaning did not resolve the problem at start up and it was in the teens this morning. The idle was extremely rough and low, it almost died a couple of times.

Does anyone know if it is just the casting that is a ford part, or if the whole assembly is a Ford part? What model and year would cross over, or even better a Ford part number would be great.

Hope to hear that someone has already explored this option and knows how to do it.
