The only thing I could find in the Bentley manual was sensor default values.
The ECU goes to a default mode if it detects an open circuit in an AC component or sensor.
That info is on page -87-3 if you have the Bentley manual

The info I used for idle specs. is from my personal notes on research I have done.
I also used my 2000s with a manual transmission as sort of a proof.
I took it for a short drive to get it to operating temp. and it falls in the same range as your car.
My 2000s is in stock tune with 52000 miles and runs excellent.
Idles AC off at 700-750 will go up about 100-150 with AC on.

After going back and rereading this thread I see you car is a 1998.
I believe your car has an "idle air control valve" as part of the throttle body.
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

Yes the code is thrown quite a bit actually, never really care since it goes away after a couple days anyways. I have looked up the valve on pelican parts, about $40 so not terrible, maybe it can be a winter project. I’ll have to locate it first and give it a look, maybe just needs a cleaning.

If The code your throwing is related to the IACV it is going to be directly related to all your running, stalling issues.
What is the code???

Last time i scanned it at the beginning of the year it was P0410 & 411, that came up more often than it does now.

Both of those codes are for issues with the secondary air injection system.
Sounds like you have multiple issues going on with the car.

Yes, the fixes for those are oxygen sensors or an air diverter valve but like i said thats from April this year( had the car a while, things tend to pop up every now and then, depending on the severity i fix them right away) I don’t see any from scanning concerning any with the IACV.
