Ok, so I just replaced my alternator about a month ago due to it not holding a charge and it fixed that problem. Then about two days later I would be driving along and when slowing down at a red light it just stalled out of nowhere. Runs fine otherwise, doesnt have a rough idle or anything so I have no clue what it could be? I've checked vaccuum lines and didn't find anything any suggestions??

Have you checked your air filter, fuel filter and you fuel pump? (Sounds like you may be having an issue getting fuel up to the rail, gravity and momentum comes in handy when your moving to help it flow along) Give it a can of B-12 Chemtool also, never hurts. Let us know how it goes for you and if none of those has fixed the problem.

*A marginal battery can cause stalling at idle. And yes, you can have a battery that is strong enough to start the engine, but marginal enough to cause havoc with the engine management system. Have your battery "load tested". Any parts store will do this for free.

*If battery checks out, then the next in line for suspects are a dirty throttle body, dirty idle air control (or faulty one), or a flaky throttle position sensor.

Ok I cleaned out my IAC and it's not stalling anymore, but my rpms are still dropping very low when I come to a stop? I'll try a new air filter next!

The fuel filter is fairly new. but I'll still check that out! Thanks guys, sorry for the late reply!
