Upon acceleration, the car runs fine. what should I do? Do I replace the spark plug connectors? One more note, this rough idle was never there prior to the plugs being replaced.

Yes, whenver you pull the coil wires off of the plugs, it is always a good idea to replace the coil wire resistor boots. They are about $7-$10 each.
