Engine sputtering after puddle hopping?

It's a 94 4.0l. Every time i go on the trail along the train tracks or anywhere else an hit puddle after puddle. Water splashes far over the hood. Then the thing starts to sputter. Like low end. If I go into first. It'll sputter until like half way thru the gear then I shift into 2nd an it does it again. I did some research an some say distributor cap an spark plugs some others say I got water in a vacuum lines. Any ideas how I can still go off roading an not worry about hitting a puddle

Splashing water over the hood is not the proper way to off road. The goal would be to enter the water slowly and ease through it with no wake.

That would solve your problem. If you still want to make huge splashes you should water proof everything. Which is nearly impossible...so just do it how you are suppose to.

I would start with the spark plug wires. Old trick was to take a water bottle and mist water until it sparks or engine rpm change. If you do it in low light you can see the electricity arc from the wire to the engine. Happens when the insulation around the plug wires go bad. If you find it is arcing replace the spark plug wires. To further water proof use DIEELECTRIC grease in all the wire caps. Helps from keeping the water getting under the cap to the metal parts.
