It's been awhile since I messed with it but I did get it running better. I think reducing the idle timing helped. I believe I ended up around 16 degrees. The AFR at idle is close to the target and it is going into closed loop learn now.

I do still have an issue with the RPM's hanging up when I let off the throttle. TPS and IAC are at 0% but RPM will hang around 2,000 until I blip the throttle and then it will return to normal idle. That has been pretty annoying. I only drove the car a couple times in the past months since it was 100+ degrees all summer here in Houston. Looking forward to getting it out more now that it has cooled off.
