reoccurring misfire

If you have the 3.0, the most common misfire cause is the factory-installed yellow-colored IMT O-rings failing. Once replaced by the new-and-improved green-colored IMT O-rings, the issue is usually resolved....
Another common cause for misfires is a cracked or improperly-closed air filter housing. Have you or someone else opened yours lately, perhaps to change the filter? Unless you first unbolt the air filter housing from the engine bay before you open it, it is very easy to break the plastic parts and create an air leak without realizing it....

With the age and miles of your car you should have replaced all the coils and plugs by this time. Have they all been replaced?? Be sure and check the plug wells for oil.
They are just wear items and slowly degrade over time.
Be sure and follow the above recommendations. The V-6 has a list of unique problems. Mainly with vacuum leaks and the IMT o-rings.
The good thing is it's all pretty minor and if you DIY it's not very expensive.
