Hey Nick!

Brownsburg here, you?

Check the wiring/coil connection nearest the air intake for getting wet.

Danville, thanks ill give that a try.

 

I am having the same problem among 480 people on google. Please post your result and let us know if it works. We are tired of giving awaying money. Thanks

 

There is a known TSB out for a bad cowl piece on the early Gen 2 D'sthat allows water to run down on the engine when water comes down the windshield.

I do not have it handy, but have seen it posted here and elsewhere.

Definately not good to have water running down on the engine.

But getting water on the engine wouldnt cause it to stall. I would lean more towards an exposed wire somewhere.

 

I have a Hemi and seen the problem. Get the garden hose out and pop the hood and see it for your self. Let the hose run water down the wind shield. It will not even slow down, right on the engine. This much water will stall any engine.
You can purchase a new redesign cowen from the dealer for around $120. Will need button kit and some RTV. Will fix the problem. If you look closely at the cowen right in front of the wind shield you will see where it is not even touching. It is like the sun warps it.

Thanks for all the good post on this forum has been most helpful.

Just one thing that I have found,

My wife's '05 with the 4.7 did the same thing. I was at wits end. I took it to my local shop and they cleaned the battery connections and put some dielectric grease on the terminals. I can now drive through 18 feet deep puddle without it stalling. Ok not really but it has solved the issue for us.

 

Moparman:

While I agree with you that a minor amount of water getting onto an engine should not be an issue, going through a car wash or putting a garden hose on your windshield is another story.

Today's engines have more and more sensitive electronic systems that make them run. Most of this is put up high in the engine compartment for just this reason.

Another topic not mentioned yet is the chance that something might crack since engines operate around 200 degrees, and having water in the 50-80 degree range dumped on it is probably not the greatest idea.
