Default 95 Blazer Rough Idle

I've got a 95 Blazer (the one with the vortec plaque on top) That I've just replaced the fuel pump, filter, and spider injector with new (not reman). And now it refuses to idle once warm. When cold the truck runs flawlessly and even when warm but it idles soooo rough when warm it sounds like it's going to die! Anyone had a problem like this? Could this be a plenum gasket leak?
