Just for grins- - - -try another set of spark plugs. If the wires are that new, no problem. Sometimes wires get neglected during an otherwise good tune up just because they don't show any external damage. At 3,000 RPM each plug wire is carrying a minimum of 10,000 volts- - - -25 times a second. The greatest challenge a spark plug or a wire ever faces is acceleration- - - -I've seen firing voltage jump from 10-15K volts at cruise to 30K or more on a hard pull when monitoring oscilloscope patterns during dyno runs. It doesn't take much fouling to make a plug miss under load, especially if it's EVER been flooded enough to get the porcelain tips wet with gasoline. I've seen "clean" looking plugs that absolutely would not let an engine run- - - -swapped plugs and it fired right up!
