Also if there was a leak on the inlet manifold would this cause a misfire on bank 1??
No! it would just over fuel!
I been thinking about your misfire, sometimes other things like water/oil can get into the pistons and cause a misfire but they will not be picked up by the ecu and be in form of a fault code! Also lack of fuel will cause a misfire, i had this on my ZT with a lpg faultly injector which i got a fault code which states 'misfire due to lack of fuel'
So you can not have any of the above!
So as yours is getting codes its got to be on the electric side, so check the wiring/earths going to the 3 coils.
Is there anyone near you who you could swap coils with just to try?, but its got to be around the same age V6 because around 2003 onwards the coil are different and dont have spark plug leads.
