Does it matter if center and outer plug leads are swapped over ? (earlier mille)
or is there a small delay in timing for outer plugs to allow for the flame front travel ? possibly one for dr rossi :dunno
this is why i am glad i only have 1 plug per cylinder lol. seriously though i expect a good look at the wiring diagram would show you which one is meant to go where
Sorry to revive an old thread but have the same issue? Anyone know what coil wiring color goes to which plug (inner vs outter) on my 2000.5 Mille with Renegade twin cans, matching chip and air-box.
