When car gets to operating temp it starts to idle rough. Before it gets to operating temp it idles great, I can pull #1, 3 & 4 plug wire off and the engine changes but when I pull off #2 wire their is no change, the plug wire does have spark. As long as you keep the car at 2500 and above the car runs great ahd has good power. I have changes the dist rotor and cap, new plug wires and fuel filter. Any suggestions.
Thanks

Are you SURE that spark plug has no spark? If so the ONLY possible causes would be
-spark plug
-spark plug wire
-ignition cap.

Everything else ignition related would affect all four cylinders. Try listening to the fuel injector to see if it's pulsing like the other ones. You may not be getting fuel.
