Default P0305 situation

Last month I was chasing down a p0304 misfire and got lucky to find the wire was completely fried, replaced all the wires and problem went away. Less than 500 miles later I'm getting a p0305 code. The plugs are less than 4K miles old. What else can cause a misfire that is something other than plugs and wires? Coil pack? 02 sensors?

Tough combination. But O2 sensors need replacement no way to clean that. I would reset it again and see what happens. But misfire need to be checked. If you can check the coil packs physically for cracks and arching, thats better or replace it.

Got up this morning and was greeted with a p1412. I'm guessing I've got water in the sai system. Makes sense since I just went through Irma

Well it's getting worse, now I'm getting a p1300, p0301, p0303, p0305 and p1412. Not sure what's going on. Everything was fine and dandy before sitting through Irma, but now it's going nuts

Any trouble shooting done? Any replacement parts? Did you reset after your prior post? Were you able to check vacuum leaks? Coil pack? O2s?

Checked for vacuum leaks a few times, can't find anything. O2's have never been replaced so I may start there. I noticed when I replaced the wires a few weeks ago that the coil pack wasn't tightened into place so it had been just bouncing around. Originally I would've thought the pack was the issue but it ran fine until the three days in the rain.

Misfires on one side only, like you have, are often caused by the O2 sensor. You might try inspecting and cleaning the connector for the O2 sensor before you replace it.
