2002 Mustang V6 3.8l Rough Throttle From Idle/Hill

If you would have swapped it with another and rechecking codes again, you could have saved your money.

yes the real test for an end user is to move the coil and see if the misfire code follows it.
your outlier may be a replacement with slightly different design or could have shorted turns.

As one coil fires two cylinders and you have a misfire only on one I would give the plug wire and plug a look at.

If this uses the same part as my Dad's old 4.2L F150 uses, then the one coil pack has all 6 cylinders on it, so you cant swap it around unless you happen to know someone with the same engine....

Agree, I would look at the plug wires.

There is more than one coil pack? I replaced the one with the six towers on it that's attached to the throttle body.

Also so are you guys suggesting I replace the spark plug wires and see if that fixed it?

Sorry I thought there were 3 coils with 2 wires going to each. Suggesting you check the wire to the misfiring cylinder not replace anything unless it test bad.
