Quick Udate

It seems it was the Autolite XP Iridiums Part#xp5364- with the stock coil & plug wires the car ran great. But with the MSD Coil & 8.5 Plug Wires it idle horribly. Completely Unusual. I wire brush cleaned my original Motorcraft Platinums & re-installed them with the MSD still installed- Car is back to normal!

Autolite XP Iridiums great on a completely stock motor- Bad on aftermarket coil & plug wires.
