3.5 stalls when stopping

[69lincolnmarkiii]

I have a 1994 Chrsyler LHS 3.5. It stalls once it warms up and you come to a stop. It also has a little bit of a ruff idel just sitting still when you start it. It always starts back up but sometimes cranks longer then it should.
I have replaced both the Cam and crank postion sensors and also the spark plugs. No effect. Fuel pressure regulator seems to be fine and does not leak into the vacume port. Anyone have any ideas here?

failing fuel pump?
fuel filter?
injectors?
plug wires?
IAC motor?
???????????

Also head gaskets are still good.

My mom's 3.3 in her 93 does this too. It only does it once and a while, though, and hasn't done it in a long time. I have no idea what the deal is. I replaced the spark plugs, PCV valve, and we had the plug wires changed. Runs smoother, but still has that fit now and then. A lot of times, when we'd floor it, it'll spew out black smoke. I usually take advantage of this when a white car decides to tailgate me.

Your tourpue converter could be locking up on you when you come down to a stop. How old is your trans, how many miles on the car, does it happene more hot then cold or vise versa.

It ended up being the stupid pointless EGR valve! Thanks for all your help.

(I was not getting much help in the LHS forum)
