This has happened to me twice now. If any water gets on the top of the intake manifold it will try to stall out. It takes quite a bit of water to do this, like 8-14 inches in 4wd at WOT. The only way it will stay running is to lightly touch the throttle, to much throttle will kill it violently. It will die as if 5-6 pistons go down. If it is idling it will die slowly surging 2-3 times back to normal idle speed. After 10-15 minitues it will be dry and function normal again. Now each time I pulled the air hat off and the filter out to make sure that there was no water in the intake. What could be causing this?

 

wait... like driving through 8-14 inches of water? well let me ask you this... do you have the stock airbox? is the air hat secured tightly? is the seal of the airhat good? how fast do you hit the water or drive though it. with water your supposed to enter it slowly and keep a constant speed. hitting it too hard will throw water everywhere in your engine compartment. mainly into your air intake. you wanna be careful with water cause if you get too much water you'll hydrolock your engine and be screwed. if your air filter got too wet it could be suffocating the engine with not enough air to fuel mixture. thats just my take on it. i haven't had that problem when i drive in that much water but ive got a cai on my rig and i dont hit the water fast...

anyone else got any ideas?

 

Entered the water doing less than 5mph. Yes my air box is secure, same with the air hat. I was thinking that it is electrical. The air box is dry inside and around the intake in the fender is dry and it will do this. This is a problem if it dies on us out hunting because of this.

 

Well driving through 8-14 inches of water could be doing it..................Why in the hell would you be wanting to do that anyway.


Anyway, usually the issue is water getting on your coil or on your alternator.

 

Well this is through mud with water standing on it on the section line, and if there is no one there to pull you out.......
Is there a way to keep water out better, there are large holes in the wheel well that let the tires fling whatever they pickup (snow, gravel, ect.) into the engine compartment. Thanks for the responses.

 

Does your distributor cap have a vent on it. If it does your drawing water in and will cause the rango to die or run rough

Ok lets set the record straight. It was either back track and take an extra 7 mile drive or drive through the mud and water (which was only 30 ft of section line) and get to dry easy ground for another 1/4 to the main road, which would you do? Any ways the distributor sounds reasonable. Is there a way to keep water off it. I was just worried as hunting season is only a couple of months away that if it happens many miles from civilization I'm screwed.

 

look on the top and see if theres a vent if there is check the auto parts store to see if they have a vent less dissy cap if they dont try taping it off

 

Ok thanks topdog.
