    If it has the original 5 liter 302 v8 then It's definitely 1-3-7-2-6-5-4-8

    It is 1-5-4-2-6-3-7-8. The other firing order is for a 351 mofided or cleveland. You can try both but I'm pretty sure I'm right. Try it and tell us who is right.

    I was backwards the 1-3-7-2-6-5-4-8 is for a 351 windsor not the cleveland. But you have a 302 anyways, also some 5.0 HO motors use the 351 firing order too. I'm still sticking with your Grand Marquis firing order being 1-5-4-2-6-3-7-8.

The engine misfires when accelerating


Depending on your Grand Marquis's mileage...it sounds like plug wires and plugs...(worn out) and or engine timing/firing order? If plug wires recently changed...the spark plug wires are in the wrong firing order...confirm the firing order from your local parts store by phone...and retrace each one...always start with #1 cylinder...hope this helps.
