    The last 4 days I've been in tahoe snowboarding and the truck was acting fine. On the drive home from tahoe to san jose after the elevation decline, it started raining very hard and I was about half way home when my engine started feeling like it was jerking itself back. It did this 9 or 10 times before I pulled off the freeway and right as I did this the check engine light came on, and the engine idle was extremely rough. I have never had this problem before and the only thing I can think of is that water is going into my URD CAI..

    Opinions?

    I didn't go through any water I was just driving on the freeway when it was pouring tigers and aligators..

    I'm gonna look @ it today since the sun seems to be coming out and take apart my intake

    Ya it almost felt like i was getting fuel cut on the free way.. Only I wasn't slamming on the gas i was only going 70 and then i dropped it down to about 55-60 mph the rest of the way home to be safe.. Checked the intake and their were no signs of water but i don't know how long it would take for the water to leave the intake. Having my buddy come over asap so we can figure out what code is going on..

    If water was going into the engine what's the do I need to fo something, will the problem take care of itself, or am I looking for damage?

    i'd imagine the maf would be affected by water in the intake way before the engine would have any issues from such a little amount of water. if the intake was submerged, then you'd have some water in the combustion chambers at some point and that would have caused an issue but just a wet filter or whatever won't cause any permanent mechanical issues, just sensor issues imo.

    so, is the truck running normal now? if so, to me it sounds like it had a simple case of exposed, wet filter which in turn screwed with your maf.

    it takes only a very very small amount of water to throw off the MAF and make your truck stutter like that.


    Do you have an aftermarket grill? The URD intake was designed to be used with a stock grill. Changing that can make a difference.

    If so, URD does sell a small filter shield that blocks water and direct wind turbulence.
