Car revs then dies after driving in water

[horizontalkev]

Drove into a flooded street that I couldn't see and died in water to just below my door.. When I got pushed out, the car turned over a million times before it started, and afterwards hasn't been the same.

Now the car will idle till the day is long but when you start to rev it, it'll suddenly cut out and die near 4k rpms... And take a good while to start again.. I changed the oil, and spark plugs and still nothing. What should I look for?

I pulled some codes. P0300 and P1103. Could a bad headgasket do this too?

MAF???

My MAF is just before my throttle body is its unlikely warter reached it

water could have been flung anywhere under the hood when you drove into the water.

po300 is a multiple misfire condition, inspect the ignition system.
pull the spark plugs and search for moisture or rust on the wires and plugs.
check the coil pack, cam angle sensor/crank position sensor
power transistor and all the wiring/connectors for these.

if you injected water the motor could of hydrolock which could of bent rods . you might have to drop the oil pan to check

You would have to injest a LOT of water to do that, and it would have to make it all the way through the turbo, intercooler, intake manifold, and into the cylinders. I'd sooner bet ignition, alternator, or something electrical fried -- not just got water in them. Alts hate water. Great time to see if you have plugs and connectors with broken tabs too . Start swapping bits.

Check all electrical connectors, check fuse box, check coils for corrosion inside were the plug wires go, check plug wires. Think spark anything ignition or spark related.

My lancer did something similar the other day, turned out to be moisture on my maf, it wasn't soaked just moist. If you haven't already solved the problem blow it out with some low pressure air for giggles

After running through a similar situation in my 1g, it turned out to be a the MAF being soaked that caused the exact symptoms, I did not get any codes thrown however. I let the car idle to get warm and attempt to evaporate any heavy moisture, your best bet is to let it dry if you can and attempt to start after.

the smallest amount of water will make my MAFT act up like a small child in the wall-mart check out line.

But water in the engine is super bad, like terminal.

i had a cold air aintake on my charger and it sucked it up like a straw hydrolocked the engine first it knocked then it locked...
