Maybe have found it, IAC connection. Pulled the plug just look at the pins. Nothing obvious wrong. So plugged it back and wiggled it a little since my contact cleaner was in the basement.

Fire it up and idle barely varied. 650-675 rpms. Noticed the IAC position is changing too. Before it would show 150 and never change. Now it hovers around 38. Turn on AC and it bumps to 56 and then drops back down to low 40's. AC off back to 38. I was assuming it couldn't read the data.

I will check it again tomorrow in the morning to be sure. But looks like the IAC just didn't have a good signal.
