The engine stumbles & dies after it warmes up. It has new plugs,wires, cap, rotor, modual, coil, fuel pump, fuel filter. I took the EGR off & it still acted the same way.

Has the check engine light come on? HAve you checked the crank sensor? If you had the EGR off, that would have created a large vacuum leak. How did you check it?
