Default Air conditioner

Why does my car sometimes feel like it wants to die when i have the ac on. It died on me one time when i had it on high but started right back up. Do i have to do adjust my idle or what? This is for my 87 gt.

Just some basic things i would check:
timing (if its advanced past stock the idle can get a little choppy)
IAC function
idle speed
throttle body is clean?
no vacuum leaks (this is a big idle quality killer)

All those are easy to check and fix most idle problems (that i can think of right now anyways)
