Not that I have seen a D-tec up close and personal, but I thought they got rid of the dual plug head with the passing of the Lima engine?

If you don't find 2 coil packs or 8 spark plug wires running around the engine, you probably only have 4 and a different year owner's manual (I hope).

(AutoZone's site was no help...couldn't find anything put together on Google, een the Rangerstation is 'members only' entrance now.)
