Phil there's so many things that could cause the problem, i.e. loose coil pack, or plug wire, one of the many sensors. I suggest taking her to the dealer.

Don't have a code scanner? That's your best bet for getting a sense for what's happening, before you take it in that is.

Got my Ranger back from service dept today. Per service manger, cracked spark plug caused by water pooling around plug... Seems strange to me but hey service light is off and truck runs great so far..

My question would be why was water pooling around the plug. Doesn't the coil pack seal down around the plug well? Maybe need a new coil pack?

Are the plugs not seal by the wire set? I thought we were a long ways past that.
Maybe the boot was leaking, but why would water get in there unless it was pressure washed?

considering he has had it a little over a year, thats a harsh assessment.

Sure would hope the seals on the plugs would last longer than a year. Refresh my memory what is the recommended plug change interval? Must be at least 50K.

 

[quirkybar8]

Man, better ease back on those river fording trips a little. Have you cleaned the engine by chance?

Plug interval is 100k, so no more than 80k in real world.

Was thinking the same thing.

Since first plug change is at 100,000 miles....if this happened, more than likely it was the engine plant if OP is being straight up with us...

This exact thing happened to me back in October of this year. Truck had ~7,000 miles on it. Water pooling around plug boot. Had to replace the plug and coil. Never been through standing water. Never power washed the engine bay. No idea how it got in there. It's been fine since, but my butt still puckers when I give it some gas when going up a hill.

Here are my trials and tribulations with that: https://www.ranger5g.com/forum/threads/shudder-at-speed-infotainment-dead.9623/

never pressure washed, I don't know how,when I ask he had no answer.

That is crazy, truthfully even pressure washed they should not leak. Not to that extent anyway. If this came from the factory as Phill states, I thought after a year the water would just evaporate from heat alone. I wish I could tear down a 2.3 engine, I would like to look to at the coolant cavities.

DO you know if the water was clean like rain water or with chemicals?

Also, even though you never pressure washed it yourself, I have seen dealerships wash engines off before a sale. Im not sure if they still do that.

Car wash much? Some of them when blowing off water can get it to come in from wiper gap
