I have a hard time blaming those symptoms on new plugs unless you dropped one or two and reset the gap. Sounds more like wires to me also. Another possibility is the plug terminal adapter caps. Sometimes they don't come with new plugs. Did you replace them? make sure they are clean/tight? I don't mean to sound condesending but sometimes the simple stuff gets by the best of us.
