I own a 1994 Lincoln Mark VIII with a 4.6 DOHC engine, 147,000 miles. I bought this car for $500 and the original owner broke off two spark plug wires off in the head in which i was able to get them out. the wires are on the drivers side and when i look at the chiltons book on how the wires are connected to the coil packs they do not correspond with the firing order.
