Whenever I first start my car up it starts to sputter and die, and for the first mile driving it feels real jerky like it is not getting any fuel. this was a problem last year but after change the plugs, wires, cap, and rotor it went away, but 6 months ago it started back up again. I have changed everything but the wires and it still does it. Any help please.

Welcome aboard,
I would check the condition of your wires to make sure none of them are burnt, I have had 3 lay on the headers and crack thru, then I discovered the wonders of wire looms. Check to make sure you don't have any vacuum leaks, but I doubt that could be the problem since you say it goes away. Also check to make sure your cat isn't clogged. Also check to make sure the TC lockup is working properly.

Ya check your vacuum lines. I had a problem with the line going from the PCV valve going behind the TB...On the far end it was cracked and sometimes it shifted enough to open the crack more and caused the car to idle real low.
