How long after driving in the rain did you notice the car running rough? Looks like the water sat in the well for quite some time by the looks of the spark plug.
Well thats ****ed.... Same spark plug that was burned up. Next step?Just for discussion sake, here are a few pictures of an OEM GT500 coil cover. You will notice that it is sealed all the way around, except for the rear, where the coil pack harness grommet passes through. Raw water should not get past the seal if the coil cover is torqued properly. The spark plugs that are usually affected by collecting water are the rear plugs. There are no seals on the coil cover fasteners, but I cannot see that much water penetrating at those locations. So that leaves the rear of the coil cover as the most likely point of entry for raw water. Looking under my hood, both passenger and driver side coil pack harnesses are angled down slightly from near the firewall to the rear of the coil cover. It is not difficult for me to make the connection between water entering the rear of the engine compartment and water ending up in the spark plug tubes.

It smells like ethanol and looks like thin oil.Is that oil down in there? What’s the end of the cop look like?
If that’s oil you need a valve cover gasket kit.

They say a picture is worth a thousand words, but I don't know if we're looking at multiple pictures of one spark plug hole or multiple spark plug holes full of motor oil. If you have not changed the plugs yet, do that. Also crank the engine over several times once all that crap falls down the cylinder when the plug is removed, unless you have a way to soak it up before pulling the plug(s).
The the plastic grommit on the coil was loose and there was moisture built up. Pulled it off wiped it down, reattached the sleeve running. Smooth again. Thank you guys, and boy do i feel foolish
