Perhaps there is an issue with it that relates so the bog problem and the issue with the AC on when stopping.

I am not familiar with the setup so I can't be of much help.
I would do a search here on the forum and a general search on the "net".

I would scan you OBDII for codes or pending codes if the CEL has not set.
Then do some research and learn what you can about idle control valve issues.

I am not saying there is an issue with it just pointing out something to look at

Blue is probably right. Pull the IACV and clean it, quite an easy job:

Nice, thank you for the link. I responded below before seeing this, said basically just clean it. I’ll see how that goes. Thanks
