lately my car is idling a lot slower ,could it be the heat.Or can my stereo system drain to much power that the spark plugs aren't getting enough spark,I have a week alternator so that does'nt help with the stereo.Thanks.

Check for a vacuum leak. When does it stall exactly?

My car used to do that when I first got it. It would just stall when deccelerating or idling. After I cleaned out the TB and IAC passage it stopped dying.
