Default I need some help

I have a 1994 Z-28 with an automatic trans. and about 130,000 miles.
The problem is when I try to start it it will start and immediatly die, after a few tries it normally starts but lopes at about 500rpm for about 45 seconds before it idles up to normal on its own. Does anyone have any clue what would cause this? I put a new fuel filter and pcv valve in it today, also I eliminated the Egr and that didnt help it either. Thanks for the help

Did you check all your plugs and wires. Could have a burnt wire maybe. Also might be the opti.

Well I just took it for a drive, I think it has something to do with fuel delivery, it was cruising fine, but when I went full throttle it started sputtering around 3700-4000 rpm, but other wise it ran fine.
