On the V6 the rocker cover gaskets are prone to leaking. The oil in the plug holes makes the ht leads break down and causes the misfires. You'll
need to sort the oil leaks first as well or you're gonna have a vicious circle/groundhog day.
Cavweb forums has a lot of info and how to's on it on this very subject.
Good luck.
If it looks wrong it probably is wrong.

As above --
Fix the oil leak first
Usually replacing the plugs or leads alone isn't enough -- need to be changed at the same time.
On a lot of engines this sort of problem can even take out the coil packs.

The cam cover gaskets aren't too bad a job but changing the HT leads is a right pain
