What is the spark plug gap for my car and firing order?

Set the spark plugs to a 0.044-inch gap and route the wires in firing order 1-4-2-5-3-6. If the engine backfires, misfires, or idles roughly after plug or wire work, recheck the coil-pack connections and wire routing against the correct diagram, confirm the wires are fully seated, and check trouble codes.
The owner of a 2005 Ford Taurus asked for the spark plug gap and firing order. An expert specified a 0.044-inch gap and firing order 1-4-2-5-3-6, with installation guidance and diagrams. Later posts about Taurus misfires, backfiring, and rough running after plug or wire work were attributed mainly to crossed or incorrectly routed wires, and experts repeatedly pointed to the same firing order and diagrams.
