I don't think the IAC is working. I removed the IAC and took a quick look with it powered by MS. When I turned the key switch, nothing happened. I plan to spend the rest of today learning how this thing works. Hopefully, I can change the coil wiring scheme and get it to work. It could be that I need to reverse polarity on one of the coils.

I don't think I'm ready for the Extra code yet. I still have a whole lot to learn about MS2.
