On our 2.0, the plug leads were causing a missfire. In the dark, I could see blue sparks around the leads.
I'm not sure what arrangement you have on a V6, but it is worth a look.

Take care poking around the engine in the dark!

Check plugs, and leads. Can try a spare plug in each lead, check for spark.
If it's not firing on two of them, will be ignition amplifier - hard to diagnose unless you're aware of it.
