03 cavy stall-HELP!

well today i was driving down the road with the a/c on and came to a stop at a red light. once stopped i felt my car shudder, almost like it was gonna stall, then it stopped. i looked at the rpm's and they were at 200 when it shuddered. it happened again right after that and my car just completely died. it restarted fine and drove just like normal after turning the a/c off. any ideas what it could be?? i was thinking either spark plugs or the a/c compressor itself. any help would be most appreciated seeing as how i live in arkansas and summer is very near and i cant go long w/o my air conditioning.

Try checking your idle air control solenoid.

I'm having the same problem with my 2002 cavalier...was just curious if it was the idle air solenoid or not?
