i think you disconnect one of the plug wires or you need to change one of them .
It could be the oxygen sensor, valves, plug wires or a sticking fuel injector. You'll have to get a little more specific. If it ran well BEFORE changing the plugs and now it doesn't, perhaps 2 of the plug wires have been cross-connected.
What else can I help you with?

Why does your truck run rough after changing the distributor cap and rotor?
Rough Engine Performance AFTER Changing Distributor Cap and RotorThe only thing I can think of is that in the process of the changeover, the wires between the newly installed rotor and the spark plugs were not reconnected to the proper "towers."As a result, the spark plugs are not firing in the proper order thus causing the rough running. Since the engine will run, I also suspect that possibly only one or two plug wires are improperly connected.
