ok here is the full story was out playing in the rain (N HOLLY CRAP WAS IT RAINING) n what i though to be just a normal intersection had some water on it didnt realize they had been doing something and had a 9 - 11 in deep section cut into the road n bam guys cuts me off n i get stuck smack dab in the middle of it not to mention that my intake is only like 4-5 inches off thee ground so naturally sucked water in i no pulled the fuel pump relay and spark plugs and hit the starter button (dont like to turn a key i am lazy) until no water was spitting out of the cylinders put everything back together and hit the button again didnt really want to start but when it did it will idle but as soon as you put any kind of load on it it just starts popping gagging and dies throws a system too rich bank one code dont remember the number just wanna know what everyone else thinks is making her not run or if i just need to lets it dry out mor this happened prob 14-16 hours ago any advice will be kindly appreciated

 

Let it idle and get up to temp. Listen for knock sounds. If no water came out when you turned it over with the plugs out, that's good. However if it did suck some water threw the engine that would be bad. Do a compression test to find out if something bad happoned.

 

Why would anyone want to mod the intake to be 4-5" off the ground?

 

ah i remember when this fun time happened with my WRX. be very careful for knocks, i let mine sit for a couple hot days, not sure if it actually helped, more of just terrified to try and start it. Its now been... 30K miles since, and no problems at all.
only thing it ended up damaging was the IACV, sorta rusted the valve not letting it idle properly. Couple videos of just sucking it up and working on it:



last one is the IACV, just took it apart, worked it till it moved properly, replaced the gasket, and wallah!

 

Do you have a MAF? or SD? I had this happen one night on a flooded road (about 2 feet of water ) and the water contaminated my MAF.

If water did get into the MAF, you will need to replace it.

 

went out to it and found water in oil not sure if it took out the head gasket or just got into the vaccum system n worked its way down there gonna trailer it home tonight n do comp test and another oil change (3rd one tryn to get all the water out of it) think its ok just gotta drop pan and clean it out but will update as i find stuff out but it will now idle n what not after oil changes so ill c what a new maf sensor is n my air intake system still has all the stock sensors n no idea y previous owner put it there but i can def tell where its not gonna be here soon

n thx 4 all the help guys

 

ok got it home n plugged into code reader n what no n its throwing codes

p0113 intake air temp sensor circuit hi input
p0102 maf / vaf circuit low input
p0107 manifold absolute pressure circuit low input
p0172 system too rich bank 1

and code reader data stream says its calculating no load and my maf stays at 0 lb/m so i am thinking i cooked a maf sensor but it runz no smoke no knock n will idle all day long until u hit the gas pedal and put any kind of load or tyr to make boost on it

 

p0113 intake air temp sensor circuit hi input
p0102 maf / vaf circuit low input

Based on the codes above, it toasted the MAF.

Im sure theres one you can find in the for sale forums on here.

p0107 manifold absolute pressure circuit low input- This may be directly related to it running poorly.

I would replace the MAF and go from there.

Also, remove your intercooler and make sure that there is no water in it as well as the piping and intake.

 

Happened to me a few months ago In my rsx. Drove through water and it shut off. Had a cold air intake and sucked in water. I changed the oil( oil had a ton of water in it) and I replaced the spark plugs). Took off the intake and didn't drive or start it for a week. Prayed and started right up. Had some smoke coming from exhaust for about 2 min then everything was ok,

 

yep after watching my cata list with the code reader and my maf is calculation 0 lbs / m and caluclating no load % gonna buy a new maf and as for intercooler i have water in it all the time lol i have upgraded to a liquid to air intercooler but pulled boost tubes and n what not pretty sure after i have been messing with it aill day yesterday and up till 3 in the morning its just a fried maf sensor

but thx for all the help guys n the quick reasponing i really do appreciate it

 

anyone no if the evo 9 maf sensor will work on a 2003 evo 8 they look the same but just wanted to make sure nothing will go wrong putting a evo 9 maf sensor on my evo 8

 

Check the part number. If they are different get the right one for your 8
