P0306 is missfire on cylinder 6 and I belive it could be caused due to a dirty MAF sensor, clean it and see if it goes away.

It was a rotten plug wire. It wasn't leaking externally?The core was rotten. How are you suspose to clean a MAF sensor when any cleaner will remove the protective coating from the wire?

Rotted core on the wire, thats a new one.

MAF sensors can be cleaned with brake cleaner, or QD contact cleaner, its recommended, it doesnt remove the protective coating, just spray it on.
