RPM drops to 500

[skyluver]

I have a 95 SL2 and had no major problems till now.
After idling with having the a/c on, the engine dies and also while
slowing down the speed I've noticed that the rpm drops almost to
around 500. Is there anyone that can explain why this is happening..
and do I have to take the car to get it fixed?
It has gotten very warm (above 75 degrees) these past few days,
wondering if the temp. would have anything to do with it.

PLEASE HELP ME!!!!!!!

If there are no codes, then start with the obvious. When were the plugs last
replaced? When was the throttle body last cleaned? How old are the wires?
Air filter? Fuel injectors? Oil level? Battery? If I had to take a guess,
assuming other stuff is in good working order, and it only shows up at idle,
then I'd clean the Throttle Body thoroughly.

Also, mileage, maintenance history, and a better symptom description might
get you a more educated guess. Good luck.
