05 F115 plugs

[pauly123]

I have a 05 fuel injected 115 hp 4 cyclinder when i take the spark plugs out the top two look brand new like they have not even fired the bottom two plugs look black and have carbon on them. Anybody know whats wrong. It runs good motor only has 28 hrs. on it.

From what I've read here, sounds like water getting in the cylinders and cleaning those plugs...

Someone else will chime in with a definitive answer...
