Ok so basically I don't use my Ac I prefer fresh air any day. But in summer time utah it gets well over 100 Degrees sometimes so I might wanna get this fixed. Just wondering what would be causing this, Ac compresser? My best guess since i've never ran into any problem with my ac in my 97 esi talon.
 
Is your profile up to date?? You have no cams? My car was having the same issue, mechanic said "might be because of the cams". With DSMLink and my tune, my RPM's have since held steady.

Before DSMLink, If I didn't play with the throttle at an intersection my car would die. Is yours stick or auto??
 
Usually my rmp idle is at 500-700 and when I turn the ac on down to about 100 i've never let it run till it dies but i'm sure it will if I let it go to long. and no I don't have cams, I haven't even gotten into anything with the motor except exhaust.. i'm still doing easy bolt ons geez
Auto tranz
 
i have the same problem on my 94 DSM, i just adjusted the BISS screw and im fine, before that i had to give it gas at stops so i wouldn't stall
