Ok...i read the full thread here and a similar thing happened to me the other day..here's the post i posted in the accord forum...

"First the cause of the problem. I originally removed my resonator which leaves my airbox open to whatever comes in the front right trim under the bumper.

Thursday night i went to a local warehouse parking lot and changed my automatic tranny fluid and was done with that. I WAS planning on doing my oil at the same time but i decided to pack up because a storm was heading in. I made a GOOD choice because it started to sprinkle JUST as i got the car off the ramps and everything in my trunk. Thank GOD!

So i decided NOT to go home right away. I wanted to see if my tranny was alright with the new fluid i put in. So i drove around a little. It starting raining harder and HARDER..REALLY HARD!!! Now it was POURING! I was driving through this parking lot with draines in the center of the lot with warehouse builidings on both sides of me. So all the water from the roofs of those warehouses were draining down into those drains. I was like "cool..thise is deep water...water spraying from my car is prety cool"....so i start going through it faster..and then one i went through REALLY fast....BIG MISTAKE!!

After that my car started to loose power and started to vibrate. I SO friggin knew what i did!!! Water splashed up into the filter and SOAKED it!!

So the check engine light came on immediatly, so i shut the car off!

I waited..and thought...thought..and thought some more.

I eventually started the engine again and seemed alright...BUT..when you hit the gas...i assume it sucks water out of the soaked filter into the engine....so it starts to vibrate again...so i let my foot off the gas. I let it idle....i think if more and more air gets sucked through the filter. It'll dry it out eventually. I was right...well...not RIGHT..but semi-right. I guessed it dried it out enuff so i could get some high rpm's to get the car moving.

I went up to the gas station under cover of the rain and look my airbox apart. Sure enuf...SOAKED!! I tried to dry most of it out...but it's still gonna be wet. So i just drove home and turned it off. Next morning it was fine. I'm pretty sure the filter has dried by now(didnt feel like taking the airbox apart again).

Just last night i changed my coolant and my oil. The car runs great and sounds great. BUT..i have a small problem...

My STUPID check engine light is on!!!! Now i have heard before that if anything is wrong with the car..obviously that light will light up. I also heard that REGARDLESS of what you do to fix the problem that had happened. The light will STAY on??? Is this correct? or is the sensors still picking up water in the intake? I am figuring i have to go to honda for them to reset it for me cuz that light is ANNOYING!!

Can i get it checked other places besides Honda? I dont wanna pay too much for them just goin in and reseting the ecu or somethin. I can do that myself. Will resetting the ecu reset that? I havent tried that yet but i might.

What is the SURE FIRE way to reset your ecu? I have heard of removing the ecu fuse...to disconecting the battery for 5 minutes....to i dont know what.

Thanx for all the help, hopefully someone will have some experience with what i'm going through, thanx!"

Now, so far my engine runs as smooth as it did before the water. My filter is now dry and the engine seems fine to me.

Would it be SMART to go to the dealer to get that compression test? They'll prolly recomend it if my check engine light is on anyway.

Any feedback would be useful, thanx!
