it has been raining here in Florida in the past few days, and today it rain so much the main road out side of my subdivision got flooded. on my way home from work, i didn't see the water and ran right through it and my car stopped in the middle of the water. i tried to restart twice, but it wouldn't start. i have installed a cold air intake so sucking up the water to the engine is the first thing came to my mind. if this is true, does this mean my engine is done? what areas should i look for water? maybe i can just use a shop vac and stuck out the water and do a oil change. i really don't want to end my car like this.

I doubt that your engine is done, but you might have to take the intake off possibly and dry things out. Did your CAI get water soaked? I take it it did. Take the intake off and dry out all components.

I don't think I would have a CAI if I were you if that's what you get to experience- not worth the fractional performance gain. I would return things to stock if I were you.

Wow im so sorry to hear that man. im from jacksonville myself and today in the heavy rain i was hoping for my CAI not to suck anything up. were u flooring it? rains insane over here. this fucking rain made my best friend total his 350z today and i was with him. thankfully we were both ok. i hope you get it figured out. good luck man :/

I'd pull all the plugs and crank it over to try and push the water out. Leave the plugs out and let it dry overnight.

I think you should be fine though as I doubt water got sucked up through the intake but I would do it just in case. Filter would have to be submerged in water to cause any problems.

you should be ok doing what spider recommended, if you accelerated a lot through the puddle then you may have a problem. I hydrolocked my engine in a big puddle in a parking lot but it was pretty massive and more of a hole in an already big puddle

When you try and start it, will it turn over?

Pull the plugs and crank it over. Once it cranks over a few times, put the plugs back in and try to start it. It's better to start it right away than let it sit with water in it. Check the oil, make sure there's no water in it. It's a good idea to change it anyway.

If it starts and everything is fine, over the next few months, listen for any abnormal sounds. Look for a CEL for misfires. Misfires following a hydrolock situation is bad news.

Define, "puddle".


Why did you try to start it? If it was full of water turning that starter can only make things worse. Insure the water is out first, then try to start it.

Too late now, I guess. Good luck.

I agree. If it's already running and there's enough water to stall it, it's probably not going to restart without getting the water out.

sounds like you locked it up. i HATE CAI's

depending how many times you tried to start it after it stalled is were you might have made the mistake....
along time ago i had 95 prelude..... did the same thing ran through a "puddle" and it stalled....... i tryd cranking and cranking and guess what i did.... through the rode through my block..... you need to get the water out before you try to start it.

I destroyed the engine in my corvette in a similar situation. Try the plug thing. Hope you get lucky. Might test the compression. If you bent a something, it might show up as a leaky cylinder.

Puddles in Fl are lakes.
When there is a "puddle" in front of my home in south florida I use my alumnium boat to get up and down the street.

thank you all for trying to help. here is what happen now.

i changed all the spark plugs and did a oil change. and trying to fire it up, but it wouldn't. the engine was turning but it just wouldn't fire up. so i grab a second battery to give it more power.(i was thinking my battery is about to die). it still didn't fire up on the first try with the second battery added on. so i give it some gas while trying to crank it. i give a a long crank(about 5sec), and it fired up. but as soon as i let go the gas, the engine shuts down. so i did the same thing again but this time it fired up right the way. i keep my foot on the gas @ 2000RPM for about a minute and the car stay on. the engine light was on so i grab my code read here is the code. all of the are related to misfire. total of 8 codes

P0180 map baro circuit High
P0302 cylinder 2 misfired
p0304 cylinder 4 misfired
p0305 cylinder 5 misfired
p0306 cylinder 6 misfired
p0300 multiple cylinder misfire
p0303 Cylinder 3 misfired
miss one code, might had been cylinder 1 misfired.

my question is what causing the cylinder to misfire since i replace all the spark plugs already and i reinstalled the coil in the order it was uninstalled. the spark plugs are NGK 6994.

It's basically what I said earlier in this thread:

When you pulled the plugs, did you crank the engine over to remove all the water? If not, the water stayed in the cylinders which would make it very hard to turn over. You added a second battery and if there was water in there and there was no damage yet, you definitely did damage that time.

The misfires after hydrolocking are usually caused from bent rods and low compression. The engine will likely spit a rod out eventually. Get the map sensor fixed and if it still runs bad and has misfires I would start looking at a new engine.

Opening the throttle raises your dynamic compression as does rpm so if it's really low from bent rods, sometimes opening the throttle gives enough that it will start.

So fix the MAP code and then do a compression test. A bent rod won't show up on a leakdown test, only a compression test.

Pull plugs and crank...changing and not removing water just makes it worse. Now the plugs arent fouled, yet, and will probably fire up. Your pistons gonna try to get to top dead center, but the water is a huge restriction. Water does not compress. Like many have mentioned, you may have had a good engine, but now you may have bent rods.

quick update. After clearing the codes, the engine light didn't come back on. i have been driving it for the past couple days, everything seems to be normal, no weird sound or other problems. i drove it at 80mph today and drove it pass 4000rpm couple time too see any problems comes up. so far no problem!!
