Buick/Olds: Car dies at idle when AC is on, 3800 engine, buick lesabre

Question
I have a 1994 buick lesabre with the 3800 engine with about 55,000 miles.  the vehicle tends to die when idleing in traffic while the AC is on.  Thank you  

Answer
Turn the AC off!
Just kidding, sorry.
Do you notice any other running problems like a hesitation or maybe a slight miss going up hills? The reason I ask is because there is usually a problem there all the time that you just happen to notice more when the AC is on because of the added load on the engine.
It is probably ignition related, like plug wires that are arcing or just worn out plugs. Possibly a coil starting to break up under a load.
