2001 5.4L moisture in Coil on Plugs causing misfire
2001 Navigator 5.4L - I had to replace one of the coils on the driver's side some time ago, and since then, I keep getting moisture under the coil cover that eventually causes a misfire. If I remove the cover and let things dry out, then the misfire goes away.
I don't drive this truck much. Where is this moisture coming from? Is it getting under the cover from outside, or is something leaking/cracked/broken internally?
