What did your plugs look like before you put in the new ones? Were they all in similar condition? If one plug stood out as being much worse, you could then isolate in fixing that one cylinder (coilpacks, leaky injectors, etc.). Coilpacks don't go all at the same time.

If they all were similarly bad, you can then start double and triple checking all the obvious stuff.. like loose couplers, vacuum line leaks, electrical grounds, etc.
